Abstract

A device for drying materials, comprising a drying chamber integrated in a closed system and a gaseous drying medium preparation unit, comprising an evaporator and a heat pump condenser, a heating element and fans, characterized in that the evaporator is located at an angle to the vertical.

Description

The iodine model refers to the area of the day and can be used for drying solid materials, for example, forest and agricultural products: kera / zhki and t, l

Known heat pump drying plant / A.; from the USSR No. 1252629, F 26V 9/06 /, containing an evaporator, a condenser, a circulation loop of a drying agent, a heater and a heat exchanger included in the circulation loop. When using this installation, a certain reduction in energy consumption is achieved, however, uniform moisture removal and the operation continuity of the installation at all stages of drying are not achieved.

A device for the drying of materials, mainly wood / application of Germany 1 3509550, F 26V 1 / pO, publ. 30.04o86 /,

containing Kaiviepy dehumidifier, included5 (K, dehumidifier, heat pump evaporator and condenser, gaseous dehumidifier processing unit, air pre-flow,

including heat exchanger and heater,

The known device makes it difficult to take moisture at the final floors — drying the material and does not ensure the continuity of the work of the exhausted system: circulating drying medium at all stages of drying, especially at the final stages.

- Ensuring the continuous operation of the saviKHyTOH system of circulation of the gaseous drying medium at all stages of drying and an increase in moisture removal at the final stages of drying. In this case, the technical result obtained when using the utility model is to increase the operating time of the evaporator in the wet mode.

The essence of the utility model is that the device for drying materials contains a drying chamber combined in a closed system and a block / juicer of a gaseous drying medium, including an evaporator and a heat pump condenser, a heating element and fans.

The utility model is characterized in that the evaporator is located at an angle to the vertical axis. Moreover, in particular cases, the angle of inclination of the evaporator depends on the size of the surface of its frontal section with a constant area of the evaporator.

In FIG. 1 and in FIG. 2 arrows show a circuit for circulating air in a closed system.

Device for drying materials contains: a whale drying chamber 1 and an air preparation unit 2, combined into a closed aistel. For air circulation using a heat-insulated casing 3, the drying chamber 1 and the air preparation unit 2 are separated from each other by a partition 4 into which the valve is mounted lattices 5 of reverse air distribution. In the air preparation unit 2, an evaporator 6 and a heat pump condenser 7 are located. The evaporator 6 is located in the lower part of the air preparation unit 2 under the angle to the vertical axis, while the evaporator 6 is equipped with a fan 8, a tray 9 is installed under the evaporator b to collect condensed moisture. The condenser 7 is located in the upper part of the air preparation unit 2 and is equipped with, for example, two circulation fans 10. In addition, a heating element 11 is located behind the condenser 7. The material to be dried 12 is located in the drying chamber 1,

The device operates as follows.

fg57 S y

.

Heating element And air preheated with heating edement Tt is circulated by fans 10 through valve grids 5 to the final chamber 1 and then to the preparation unit 2, After reaching the temperature required for the drying process, the heating element is switched on. Heated air passing through drying chamber 1, evaporates moisture from the material to be dried 12. At the same time, air humidity increases and the temperature decreases. Chilled and moistened

air through the valve grilles 5 enters the air preparation unit 2, where it is partially sucked up by the fan 8 to the evaporator b, and partially passes by the evaporator 6. When part of the air flow passes through the evaporator b, the moisture contained in it condenses and flows into the drip tray 9, when In this passage through the evaporator b, the air is drained. The air passing through the evaporator b is drained, the air in front of the condenser 7 is mixed with the air passing by the evaporator b, into a single stream that is circulated using fans 10 are sucked into the condenser 7, superheated refrigerant vapor is fed into the tube space of the condenser 7. Circulation flow B03jiyxa passing through the condenser. 7, heats up to operating temperature and through valve sieves 1 Ш 5 is supplied to the drying chamber 1, 1 jacle is repeated until the drying process is completed,

Depending on the properties of the material to be dried, the necessary rare drying is selected by varying the operating time of the evaporator in 1 wide mode, which depends on the angle of inclination of the evaporator. In this case, the angle of inclination is selected depending on the size of the frontal surface; on the cross section of the evaporator with a constant area. In practice, the choice of the angle of the evaporator is made depending on the type, material to be dried, the ratio of the size of the evaporator and other parameters.
