Description

The utility model relates to drying equipment and can be used in various industries to extract the water fraction from various plant materials, for example, wood, fruits, vegetables, etc.

A known installation for condensation drying of lumber contains a housing, a drying chamber with pallets located inside the housing, an air duct with a fan, a condensation and heating chamber are additionally installed in the housing, which are connected by an air duct to the drying chamber, wherein the air duct is a closed loop, and the condensation and heating the chambers contain at least one thermoelectric module, on which radiators with a heat-insulating layer are installed on both sides, located in a condensation and heating chamber, as well as in a stabilization circuit with a fan, and a control unit is introduced, which is connected to the thermoelectric modules, fans, condensation and heating chambers and a drying chamber (RF utility model patent No. 112987, published July 27, 2011).

Other similar technical solutions are also known, for example, RU 2362100, RU 17857, RU 2194229, RU 299211, RU 112987, RU 2116591, RU 2633977, RU 107333, RU 2206842, RU 2115075.

As a result of patent information research, the following foreign technical solutions in this field of technology were additionally identified: US 20170146294, WO/2015/19196, DE 19605393, FR 491200, CN 206891051, WO 2007102792, CN 106595239.

As a result of the analysis of the identified technical solutions, the closest technical solution, chosen by the applicant as a prototype based on the totality of essential features, is an installation for drying lumber, containing a heat-insulated sealed housing, divided by a partition into a drying chamber for a stack of lumber with air ducts formed in it, sensors placed in it to control temperature and humidity, and to a hardware unit, including a control system for the operation of the installation, connected to the specified sensors, a device for heating the agent transported by fans installed in the upper part of the partition into the drying chamber, a condensing fan with a drive and a condensing device with a closed cooling circuit and a tray for collecting condensate, an additional heating unit is introduced into the hardware unit, with the possibility of connecting it to an additional condenser, as well as a temperature sensor in the drying chamber, and in the upper part of the rear wall of the drying chamber there are two symmetrically located ventilation windows, equipped with dampers controlled by humidity sensor signal (RF utility model patent 44802, publ. March 27, 2005).

The known device makes it possible to isolate the aqueous fraction by condensation. The disadvantage of the known device is the complexity of the design.

The technical task of the claimed utility model is to simplify the design of the camera.

The technical problem is achieved by the fact that the chamber for separating the water fraction from plant raw materials during the drying process contains a heat-insulated sealed housing containing side and end walls and a ceiling, which houses a rack of materials with air ducts formed in it, a fan with a drive, a heater, a moisture condenser and a tray for collecting condensate, characterized in that the moisture condenser is located at the level of the housing ceiling and is a cone-shaped container inserted into the chamber with a cone, and the upper surface of the cone-shaped container is in contact with the external environment, and the inner surface has the possibility of contact with the coolant of the chamber, while the tray is located under a cone-shaped container and has a pipeline for removing the water fraction from the chamber; the cone-shaped container is equipped with pipes.

The chamber is additionally equipped with a low-frequency emitter with a low-frequency generator.

A comparison of the claimed utility model with the prototype shows that it differs in the following features:

- the moisture condenser is located at the level of the housing ceiling;

- the moisture condenser is a cone-shaped container placed with a cone into the chamber;

the upper surface of the cone-shaped container is in contact with the external environment;

the inner surface of the cone-shaped container has the possibility of contact with the coolant of the chamber;

- the tray is located under the cone-shaped container;

- the pan has a pipeline for removing condensate from the chamber;

- the cone-shaped container is equipped with pipes for filling and draining coolant.

Therefore, we can assume that the claimed utility model meets the “novelty” criterion.

The utility model can be made on standard equipment using known technological processes, so it meets the “industrial applicability” criterion.

The figure schematically shows the inventive device.

The chamber contains a thermally insulated housing 1 with side and end walls and a ceiling. Housing 1 contains a heat-heating element 6, a fan 7, which is driven by an engine 8. A low-frequency emitter 9 and a low-frequency generator 10 are additionally installed in the chamber, which are connected to each other by a conductor 11. At the ceiling level of the housing 1 there is a moisture condenser 12 made in the form a cone-shaped container, which is inserted with a cone into the chamber and has pipes 14 and 15 for filling and draining the coolant (the liquid level is indicated by position 13). A design feature is that the upper surface of the cone-shaped container 12 is in contact with the external environment, and the inner surface has the possibility of contact with the coolant of the chamber. The cone-shaped container 12 can be made, for example, of thin-walled stainless steel or glass. Housing 1 also has a valve 16 for removing excess coolant. The pan 17 for collecting condensate is located under the moisture condenser 12 and has a pipeline 18 for removing the condensed water fraction from the chamber into the tank 19.

A rack with plant raw materials is rolled into building 1 on a trolley 2. The figure shows a rack with a stack of lumber 5 on a trolley 2, with wheels 4, which moves along rail guides 3. If vegetables, fruits, berries or herbs are used, they are placed on the rack in trays.

The device works as follows.

The plant material on the trolley 2 along the rail guides 3 is rolled into the body 1 of the drying chamber, then the doors are hermetically closed (not shown in the figure). Next, the heating element 6 is turned on, the fan 7 is driven into rotation by the engine 8 and creates flows of heated coolant in the chamber, which heats the plant material. At the same time, the low-frequency generator 10 is put into operation and low-frequency signals generated by the generator 10 in the range of 5-20 Hz are sent via wire 11 to the emitter 9. Low-frequency electromagnetic vibrations affect water dipoles and lead to a decrease in the surface tension coefficient and, as a result, significantly improve the evaporation of water from plant materials.

In winter, the upper surface of the cone-shaped container 12 is cooled by external cold air, and in the warm season, cold running water is supplied through pipe 14, the excess of which is removed through pipe 15, which is located on the water level line 13.

Cold water or cold air cools the cone-shaped container 12. The water inside the drying chamber in the form of a steam mixture with warm air comes into contact with the cold cone-shaped container 12, condenses on its lower surface and rolls down the cone into the tray 17, and water through the pipeline 18 the fraction is discharged into the external tank 19. Excess coolant is removed from the housing through valve 16.

Thus, the claimed utility model makes it possible to simplify the design of the device by simplifying the design of the capacitor and its location.
