Herbal meal (granules) line up to 4 t/h
Herbal flour is a valuable protein and vitamin supplement for animal feeds, vitamin and protein feed obtained from artificially dried herbs. It is prepared from freshly cut greens with short-term exposure to heated air, which minimally affects the preservation of vitamins and nutrients available in the grass.
The processed raw materials subjected to granulation are called vitamin and herbal flour. The components for this mixture are various types of legumes and cereals.
Appointment of the technological line for the production of HTM
The line for the production of vitamin-herbal flour is intended for the production of vitamin-herbal flour or feed granules from dried grass mass (cereals, legumes, leguminous crops, etc.) by preparing, drying and granulating the mass.
Raw materials and products
Cereals, legumes, legumes, seeded annual and perennial grasses, meadow grasses with a high protein content (alfalfa is the most common).
The finished product is herbal granules:
- diameter 8 – 12 mm;
- density 0.8-1.1 kg/dm. cubic;
- crumbability from 5-22%.
VTM manufacturing technology
Artificial drying and granulation – a complex process that ensures the preservation of up to 95% of nutrients. To ensure a high quality product, grass with a high protein content is required in the initial phase of the growing season. If all technological conditions are observed, it is possible to obtain a high-quality product.
Main technological stages of VTM production
The technological process for the production of herbal flour is as follows.
Mown and chopped grass mass is fed into a drum dryer, where it is artificially dried in a high-temperature mode in a short period of time. The humidity of the product is brought to 10-12%. This processing technology (artificial drying) ensures maximum preservation of nutrients in the final product - grass meal. The presence of protein, carotene, folic acid and various microelements in it effectively influences the productivity of feeding animals and birds.
Requirements for processed raw materials - the grass mass entering production must be crushed to an average length of 30 mm and a thickness of no more than 6 mm. Particles up to 30 mm long should make up at least 80% of the total mass, and up to 80 mm long – no more than 20%. To ensure the declared productivity of the line, the moisture content of the green mass of legumes (alfalfa) entering the processing should be no more than 55%. There should be no foreign objects in the mass (stones, metal parts, etc.) that can cause the unit to break down or stop. The presence of mineral contaminants in the biomass should not exceed 0.8% in terms of dry weight.
- preparation of raw materials: mowing and drying the grass mass, chopping;
- supply of raw materials to the storage hopper;
- drying the mass on a drum dryer;
- additional grinding of dry mass in a hammer crusher;
- granulating the mass into a granule;
- cooling the granules on a counterflow cooler;
- supply of granules to the storage hopper of finished products.

Composition of the production line (PLANT EQUIPMENT)
1. Reception of raw materials
Raw materials from the warehouse enter the STOCKER BUNKER with a SCRAPER CONVEYOR, and then the wet raw materials are fed into the drying unit.
2. Drying
IN A DRUM DRYER with a heat generator the raw materials are kept for 5 to 12 hours at a temperature of 30 to 40 degrees (the air is heated and pumped into the drum). During the drying process, the grass loses moisture and reaches a humidity of 12-15%;
3. Crushing
The dried product is transported to a HAMMER CRUSHER, where crushing (grinding) up to 1-3 mm occurs using hammers, which break the raw material into small parts until the particles can pass through a sieve with given cell size. The material is unloaded through a pneumatic hose or using a conveyor.
4. Granulation
The crushed and crushed raw materials are transferred to the receiving hopper of the GRANULATOR, where granules are formed. The crushed herb is steamed in the mixer and goes to the pressing unit. Working parts of the camera – These are a rotating ring die and press rolls. The raw material enters the wedge between the inner surface of the matrix and the roller, pressure is created, and the raw material passes through the holes of the matrix (die). They come out from the outside of the matrix and are cut with a static knife (for granules: 6 - 8 mm).
5. Cooling
The pressing process occurs at high temperature and pressure. To obtain durable pellets, they must be cooled immediately after leaving the granulator to avoid large losses of carotene, so the herbal pellets are transferred to a COOLER.
With a counter flow of cold air, the product is cooled to ambient temperature and falls on the sifting table.
6. Sifting
At the SIEVING TABLE the bulk is separated from the quality granules, and small unpressed particles are also screened out here, which are subsequently sent for granulation again. Dropout percentage measures the efficiency of granulation.
7. Packing, shipment, storage
The quality granules end up in the PACKING AND SHIPPING BLOCK.
Terminal station – weighing dispenser, finished product hopper and packaging. Most often, three-layer craft bags of 30-50, or big bags, are used for packaging. For large bulk deliveries, the pellets are usually not packaged but loaded into a vehicle hopper. The finished and packaged product is transported to warehouses for storage.
The best storage conditions for herbal flour are achieved by granulating it. Herbal granules are easily transported and can be stored for a long time.
Dark rooms with good air circulation are suitable for storing herbal granules. The best temperature for a warehouse – 2-4 ° C, and the level of air humidity – 65-75%.
8. Control system
Control, management, and observation of the technological process are provided by CONTROL CABINETS and a personal computer, which controls production processes, the movement and movement of raw materials and the resulting product – grass pellets.
For the production of vitamin-herbal flour, depending on the source raw materials and the required amount of processed product, we can offer several options for assembling technological lines.
Depending on the wishes of the buyer, full automation of production can be performed, with the implementation of process control from a personal computer.

- In the drying drum (3), moisture exchange occurs between the coolant and the dried biomass, uniformly supplied from the receiver - raw material dispenser (1).
- In the drying drum (3), moisture exchange occurs between the coolant and the dried biomass, uniformly supplied from the receiver - raw material dispenser (1).
- The coolant is transported in a stream using a smoke exhauster (5) to the cyclone (4) where the product is separated from the coolant flow.
- The waste coolant (air saturated with water vapor) is released into the atmosphere through a chimney.
- The dried material is fed to the grinder (6), then ground to a fraction of 0.1-0.5 of the diameter of the matrix holes and, through a pneumatic transport system (7) and conveyor (8), fed into the operational hopper (10).
- The crushed biomass is dosed into the granulator (11) where it is compressed and granules are formed.
- Then the granules are transported to the cooler (12), where they are blown with air for cooling, dust and non-granulated mass are fed back to the hopper via a pneumatic transport system (9).
- Then they are moved by a vertical conveyor (13) to the finished product bunker (14).
Depending on the type of fuel consumed, the production line is equipped with heat generators running on solid or gas fuel.
