Description

THERMODYNAMIC DRYING CHAMBER

The utility model relates to installations for drying bulk food products and can be used in the food industry for drying molded semi-finished products of post-alcohol stillage.

A known installation for drying bulk food products (see RF patent, class A 23 B 7/02, F 26 B 17/04, No. 1162400, publ. 06/23/85. Bull. No. 23), containing a drying chamber with conveyor belts and heat ventilation equipment, a scraper chain conveyor, a scraper belt conveyor for loading the drying chamber.

A known dryer for plant materials (see RF patent, class F 26 B 15/04, No. 1451500, publ. 09.01.87, bull. No. 2), containing a chamber with loading and unloading devices and closed conveyors in tiers, placed inside it, united in the upper and lower groups. The upper groups of conveyors are equipped with individual drives and are offset from one another in the direction from top to bottom.

Known conveyor dryer for bulk materials (see RF patent, class F 26 In 17/04, No. 1615505. Publ. 23.12.90, bull. No. 47), comprising a housing with closed horizontal mesh conveyor belts located therein, equipped with drive drums and scrapers rigidly attached to the tapes. The drive drums are hollow and equipped with a stationary air chamber connected to a heat carrier source.

The reasons that impede the achievement of the technical result indicated below when using known devices include the fact that the known devices do not provide effective drying of bulk materials due to the lack of control over the humidity of the dry material and control of the coolant supply to the device body.

The essence of the utility model is that the individual drives of the horizontal conveyors are made variable in rotation speed, and the horizontal conveyors themselves are equipped with mixing devices for the bulk materials located on the conveyor belt and devices for controlling the moisture content of bulk materials. Heat transfer devices are made of pipes with a ribbed surface connected to a steam source at one end and to electric valves at the other end, and the electric valves and individual adjustable drives of horizontal conveyors are controlled by moisture control devices for bulk materials.

Using the proposed utility model provides the following technical result:

increasing the drying efficiency of bulk materials through moisture control.

The specified technical result in the implementation of the utility model is achieved by the fact that the thermodynamic drying chamber comprises a housing with loading and unloading devices with closed horizontal conveyors located in it, equipped with individual drives, devices for supplying coolants.

The peculiarity lies in the fact that the individual drives of the horizontal conveyors are made variable in speed of rotation, while the horizontal conveyors themselves are equipped with mixing devices located on the conveyor belt and devices for controlling the moisture content of bulk materials, and the coolant devices are made of pipes with a ribbed surface connected to a steam source from one end and to electric shutters from the other end, moreover, electric shutters and individual drives of horizontal conveyors directs humidity control devices.

An analysis of the state of the art by the applicant, including a search by patents and scientific and technical sources of information and identification of sources containing information about analogues of the claimed utility model, made it possible to establish that the applicant did not find an analog characterized by features identical to all the essential features of the claimed utility model. The definition from the list of identified analogues of the prototype, as

the analogue closest in the aggregate of essential features, it was possible to identify the aggregate of significant distinguishing features in relation to the applicant’s perceived technical result in the claimed utility model set forth in the utility model formula.

Therefore, the claimed utility model and device for its implementation meets the condition of "novelty.

The design of the utility model is shown in the drawing.

The thermodynamic drying chamber consists of a housing 1, a loading device 2, closed horizontal conveyors 3, 4, 5, 6 and 7, pipes with a ribbed surface for supplying the heat carrier 8, individual adjustable electric drives 9 and 10, a mixing device 11, a steam supply pipe 12, a pipeline steam outlet 13, valves 14, valves with an electric actuator 15, wet air suction system 16, a device for unloading bulk materials from a housing 17, a regulation device 18 of the amount of moist air sucked from the housing 1, arrangement PTS humidity control bulk material 19.

Thermodynamic drying chamber operates as follows.

Material for drying, for example, in the form of granules, through a loading device 2 enters the belt of a closed horizontal conveyor 3. Each conveyor is equipped with an individually adjustable electric drive 9 and 10, which ensure the movement of the conveyor belt in predetermined modes. The drying material, evenly distributed over the surface of the conveyor belt, passes moisture control using a moisture control device for bulk materials 19. In order to prevent the drying of the drying particles of material from each other, the mixing device 11 provides for agitating the material on the surface of the conveyor belt. The drying of the material is provided by hot air heated on the surface of the pipes with a ribbed surface for supplying the coolant 8, through which steam is passed. The intensity of steam passage through the pipes is regulated by valves with an electric actuator 15. After passing the first stage of drying in a closed horizontal

conveyor 3, drying particles of material are dumped onto conveyor 4, and then onto conveyors 5, 6 and 7, respectively.

Moisture control devices for bulk materials 19, depending on the degree of moisture of the material, issue a command and set the rotation speed of individual adjustable electric drives 9, 10, and also through the valves with electric actuators 15 control the flow rate of passing steam through pipes with a ribbed surface for supplying coolant 8.

In addition, the device 18 controls the amount of sucked out of the housing 1 of moist air maintains the required temperature and humidity in the device.

Thus, the use of a mixing device 11, a moisture control device for bulk materials 19, individual adjustable electric drives 9 and 10, as well as valves with an electric actuator 15 in the proposed thermodynamic drying chamber, allows you to control the drying process, save heat carrier flow, and also produce products with a given percentage of moisture , which significantly affects the quality and duration of storage.

Thus, the above description demonstrates the fulfillment of the following set of conditions when using the claimed utility model:

- a tool embodying the claimed utility model, in its implementation is intended for drying bulk materials;

for the claimed method in the form as described in the stated utility model formula, the possibility of its implementation using the means and methods described in the application is confirmed;

a tool embodying the claimed utility model in the implementation is capable of ensuring the achievement of the technical objectives perceived by the applicant. Therefore, the claimed utility model meets the condition of "industrial applicability.
