Construction and installation team, repair plant manager. Grain cleaning and drying complexes. ZAV grain cleaning complexes

Grain processing is a multi-stage process and consists of the following steps: preliminary cleaning, temporary grain storage, drying, secondary cleaning, sorting. If the grain is cleaned poorly, you can lose up to 20% of the harvest. To avoid losses, you need a high-quality ZAV grain cleaning complex, which contains a set of equipment and machines installed and connected into a common production line, consisting of two sections.

1. The grain mass enters the first compartment, where it is cleaned from large and small impurities, as well as temporary storage in ventilated bins.
2. In the second department, the grain mass undergoes final cleaning and grain fractions are distributed into bins with further unloading of grain into vehicles.

From the dam pit, the grain enters the conveyor, which directs the grain mass into the elevator. Next, the pre-cleaning machine is connected. After this, the grain mass enters a mesh conveyor, where the process of separating the remaining spikelets and straw from the grain occurs. Afterwards, the grain undergoes air and wind cleaning. As a result, light impurities end up in the waste bin. And the grain goes through a elevator into a temporary storage chamber.

Since the standard ZAV design was initially designed on the principle of modules, there are several options for the execution of ZAVs. The Veles LLC company offers you the production of three types of modules: ZAV-10 (consists of two bunkers), ZAV-20 (includes three bunkers), ZAV-40 (of four bunkers) and ZAV-100 (includes six bunkers).

The ZAV grain cleaning complex is designed for the primary processing of grain crops. The ZAV complex is equipped with a whole chain of equipment combined into one production line. The ZAV complex carries out three stages of grain cleaning: preliminary, primary and secondary.

The KZS is intended for receiving grains with their subsequent cleaning and drying. GSCs consist of two parts: a grain cleaning complex (GCC) and a dryer. The main unit of the KZS is the drying machine, which receives grain after primary processing. Depending on the technology, the KZS provides several variations of grain processing: parallel, sequential, repeated drying. The construction of the KZS is carried out in the shortest possible time - the structure is an assembly of metal parts with installed drying equipment.

Our company offers you turnkey production of ZAV/KZS complexes in any region of Russia. The most common options in Russia are the ZAV-10 complex with two bunkers and the ZAV-20 complex, which includes 3 bunkers.

ZAV-10

The ZAV-10 grain cleaning complex consists of 6 columns and two bunkers, each of which holds 20 tons. One of the bunkers is divided into two parts. One of the bunkers is divided equally into two parts. One part is intended for dust and large waste, and the second is for fodder. The second bunker stores cleaned grain.

A milking machine measuring 10x6 square meters is installed above the bunkers. The grain cleaning complex ZAV-10 includes a dam pit. To protect from precipitation, the pit is covered with a roof.

The ZAV-10 complex is suitable for small farms with up to 3 tons of grain per season.

ZAV-20

The ZAV-20 grain cleaning complex consists of three bunkers with a capacity of 20 tons each. One part is intended for dust and large waste, and the second is for fodder. The second and third bins store cleaned grain. The passage height under the bunker is 3.6 meters, which will be sufficient for almost all existing grain carriers.

The grain cleaning complex also includes a dam pit covered with a lid, which is designed to protect it from precipitation.

The ZAV-20 complex is suitable for small farms with up to 5-6 tons of grain per season.

Advantages of ZAV-20 over ZAV-10

• ZAV-20 can accommodate 40 tons of grain at a time, which is twice the capacity of the ZAV-10 grain cleaning complex;
• simultaneous loading of grain into a car and into a trailer;
• ZAV-20 has a more rigid and therefore reliable design;
• it is possible to install additional equipment, for example, for seed preparation.

Modern business and farm managers are interested in making good profits. After all, the harvested crop must be properly cleaned, processed and stored. To achieve this goal, entrepreneurs must have high-quality modern equipment capable of cleaning heavily contaminated wet or dry grain of grown crops.

The profitability and reputation of the agricultural producer depends on how well the grain is processed. In this regard, profitable farming requires the mandatory presence of a grain cleaning complex on the farm.

Why does a farm need a grain cleaning complex?

The grain cleaning complex allows the agricultural enterprise to be competitive in the market. The main purpose of the grain complex is grain cleaning, which determines its quality.

Various types of agricultural crops for food and feed purposes, such as grains, legumes, cereals and other crops, are cleaned of impurities that differ from grain in their size and aerodynamic properties. Grain cleaning is done using special machines.

There are several types of impurities:

• Grain impurities - contain unripe, damaged and sprouted grains, as well as grains spoiled by pests.
• Weed impurities - contain soil, stems and leaves, sand, and pests.
• Harmful impurities - contain hazardous substances harmful to humans and animals. These include poisonous plants and other impurities.

Cleaning grain increases its shelf life, reduces its moisture content and the number of microorganisms, and improves the quality of grain.

Grain cleaning machines included in any grain complex allow grain to go through several stages of cleaning:

• Preliminary;
• Primary;
• Secondary.

Preliminary stage of grain cleaning is an auxiliary operation. Pre-treatment cleans the grain from large impurities, due to which its flowability increases and the movement of grain in the grain dryer becomes easier. Machines for pre-cleaning grain are called heap cleaners.

Pre-cleaning is carried out immediately after harvesting. This operation cannot be delayed, because self-heating of the grain may occur, which increases its moisture content and reduces quality.


Primary stage of grain cleaning consists in separating the maximum amount of impurities, both large and small, from the main grain. Here the grain is separated in air sieve machines according to its aerodynamic properties, width and thickness. Grain is sorted by length using triers. Primary processing of grain is carried out at its maximum humidity (18%).


Secondary stage of grain cleaning carried out by complex air-sieve machines. These machines process seed material. Seed cleaning after such treatment must correspond to class 1 and 2 cleanliness.

Secondary cleaning machines distribute the grain mass into four fractions:

• Grain 1st grade;
• Grain 2 grades;
• Large impurities;
• Small impurities.

For secondary cleaning, the machines operate in three tiers, as a result of which small impurities are separated almost completely, and the resulting grain is of very good quality.

However, there are some types of impurities (sprouted or underdeveloped seeds, seeds of some types of weeds, smut grains) that cannot be removed by air screen machines. These difficult-to-separate impurities are similar to valuable grain in both aerodynamic properties and size.

To separate such impurities, special cleaning methods are used. As a rule, the finishing of grain, or calibration, is carried out by separators.

ZAV grain cleaning complexes

The ZAV complex is used for processing the harvested grain crops, cereals, and oilseeds. This complex includes a whole set of machines and equipment that are connected into one production line, making up two departments.

First department Designed for preliminary cleaning of grain mass from impurities, both large and small. Here the grain is temporarily stored in ventilated bunkers. This compartment contains a vehicle unloader, a dump pit, an intermediate conveyor, two elevators, and a compartment for storing grain mass. This also includes a pre-cleaning machine.

Second department designed for final grain cleaning, distribution of fractions into different bunkers, as well as for their further unloading into vehicles. This compartment includes a wind screen cleaning machine, trier blocks, grain lines and an aspiration system.

Operating principle of the ZAV grain cleaning complex

The grain mass first falls into the dam pit. From there it moves onto a conveyor, which redirects it to the elevator. Next, the grain undergoes preliminary cleaning in the machine.

The next stage is that the grain enters the mesh conveyor. Here large impurities, such as straw, spikelets and other debris, are separated from the main grain mass.

Next, the grain is subjected to air-wind cleaning, where it is cleared of light impurities. Impurities are removed outside where they are transferred to the waste bin. The main grain mass is poured into a bucket into a compartment for temporary storage.

From the temporary storage compartment, the grain is moved to the grain cleaning machine via a conveyor and elevator for its final cleaning. With the help of air flow and sieves, the grain is divided into three fractions: purified grain, intermediate fraction and waste. The intermediate fraction is sent for triering. If the grain mass is slightly clogged, then it is divided into clean grain and feed waste. If seed material is processed, then the entire grain mass is sent for triering.

Before starting work on the ZAV grain cleaning complex, it is necessary to draw up a diagram of the operation of the unit. This is done so that the whole set of machines and equipment included in this complex can work autonomously. When drawing up a scheme, it is necessary to take into account not only the type of crop being processed, but also its humidity, contamination, as well as the final purpose of processing.

KZS grain cleaning complexes

The KZS grain cleaning complex, like the ZAV, is a set of machines and equipment balanced in terms of productivity.

The use of the KZS grain drying complex allows you to obtain a high-quality product that can be stored for quite a long time. The harvest taken from the fields undergoes preliminary cleaning and drying of the grain and is transported for subsequent processing or storage.

KZS grain complexes consist of a receiving department, which is a dam pit with a conveyor and elevators. The complexes also have a grain cleaning department, which includes preliminary and primary cleaning machines, trier blocks and transport devices, a drying department, conveyors, grain pipelines, aerated temporary storage bins, a computer control system and a control system for all equipment.

How does the KZS grain drying complex work?

After harvesting, the grain mass falls into a waste pit, from where it is conveyed by elevator to a machine for preliminary cleaning, where large impurities, straw and other remains of plant stems are separated.

Next, the wet grain enters the grain dryer, and the dry part of the grain is delivered for storage in special compartments of aerated bunkers. From the grain dryer, the bulk of the grain, which has the required moisture content, is sent to the machine for primary cleaning, then to the trier block.

The next stage is the bunker compartment, from where clean grain is loaded into vehicles.

Seed grains undergo further additional processing, which includes cleaning and sorting using secondary cleaning machines.

KZS grain drying complexes provide the ability to fully prepare grain for subsequent processing and storage.

Modern equipment of the KZS grain cleaning complex is designed to perform both complex and individual operations. Grains are dried at the KZS only when the grain does not need to be cleaned.

Grain is loaded into the KZS, which already has the moisture level required for storage, but needs to be thoroughly cleaned of impurities.

The grain loaded into the KZS is dried by streams of hot air supplied by fans. Next, the finished grain is sent for storage or production, where it is ground into flour or compound feed for livestock is prepared.

Features of the ZAV and KZS complexes

Grain cleaning complex ZAV is a closed production line where preliminary, primary and secondary purification of both grains, legumes, and oilseeds takes place.

Grain cleaning complex KZS is a combination of a grain cleaning complex with a productive drying unit. This combination makes it possible to process agricultural crops in a full cycle until they are fully ready for wholesale sales.

The ZAV grain cleaning complex is designed to perform both preliminary and primary cleaning of grain after removal of large and small impurities in grain cleaning and grain drying lines, triremes, and other equipment.

These complexes are equipped with vibrating centrifugal and flat screen separators, and conveyors.

The KZS grain cleaning and drying complex is designed to perform the following modes:

• Cleaning without drying;
• Drying without cleaning;
• Drying after cleaning;
• Cleaning after drying;
• Cleaning before and after drying.

This complex has two departments: cleansing And drying.

The cleaning department is a typical 3-hopper ZAV, and the drying department has grain dryers and additional equipment for communication with the cleaning department: elevators, conveyors.

conclusions

Grain cleaning complexes are designed for post-harvest processing, pre-cleaning and drying of grain, as well as for its preparation for further storage. Grain complexes transport grain both internally and externally, moving it to production or into storage tanks.

Such complexes are good because they are used both in small farms and in large agro-industrial complexes.

Depending on the moisture content of the grain and its purpose, grain cleaning and drying complexes are equipped with additional equipment. The choice of equipment is determined by two main criteria: the scale of the enterprise and its tasks.

Thus, any farm can use any grain cleaning complex ZAV or KZS, at its own discretion and purpose, and select the optimal equipment for itself.

Post-harvest processing allows you to obtain high-quality grain that meets market requirements and, if certain conditions are met, can be stored for a long time. This is achieved using a set of machines, which has a common name - a grain cleaning and drying complex (GDC).

How do Grain Cleaning and Drying Complexes (GDC) work?

Grain cleaning and drying complexes can be used at various facilities. They may differ in power and functionality.

KZS cleans and dries various types of grain (seed, feed, food).

Immediately after the harvest is harvested, all agricultural crops are promptly sent to special lines for post-harvest processing of elevators and granaries. In the KZS, grain is cleaned from foreign impurities and grain is dried to storage standards. Modern equipment can perform both complex and individual operations.

• Reception of contaminated and dry grain crops for cleaning, storage and loading onto road transport.

PRINCIPLE OF OPERATION

• Grain is unloaded from a machine installed on a vehicle unloader into a dam pit;
• by elevator, the grain is fed to a pre-cleaning machine, where coarse, strawy impurities are separated from the grain mass;
• The cleaned mass, if necessary, enters the grain dryer, and the rest of the grain goes to the active ventilation silo department for storage;
• Grains that have reached standard humidity in the grain dryer are cleaned of impurities in a primary cleaning machine;
• Clean grain mass and waste flow by gravity into the silo department or are loaded into vehicles;

Seed grain crops, if additional processing is necessary, are cleaned and sorted using secondary cleaning machines.
