Abstract

FIELD: agricultural engineering.

SUBSTANCE: invention relates to agricultural engineering, in particular, to apparatus for drying fruits and vegetables. Apparatus comprises a cylindrical body, a removable drying unit, a control unit, heating elements, a fan, and a cover. The body is made hollow and coated in a layer of insulating material. The drying unit is installed in the body. The cover is made swinging. The fan and the heating elements are installed in the lower part between the walls of the body. Nozzles are installed on the inner walls of the body. The drying unit is composed of disks arranged horizontally equidistant from each other, with rings installed rigidly along the edge of the upper part of said disks. The nozzles are installed evenly over the disks along the inner surface of the body.

EFFECT: higher quality of drying fruits and vegetables with a reduction in heat loss.

Description

The invention relates to agricultural engineering, in particular to devices for drying fruits and vegetables.

Known dryer with rotary trays for fruits and vegetables [Dryer with rotary trays for fruits and vegetables. - Patent RU 162042. - Publ. 05/20/2016, Bull. No. 14], which includes a removable drying unit, housing, control, heating element and fan. The drying unit is rotatable relative to the housing.

Known dryer has disadvantages - low quality drying, which is uneven supply of heat to the processed product, and large heat losses.

The technical result achieved by using the invention is to improve the quality of drying fruits and vegetables, as well as to reduce heat losses.

The technical result is achieved by the fact that the device contains a cylindrical body, a removable drying unit, a control device, heating elements, a fan and a cover. The body is made hollow and covered from the outside with a layer of heat-insulating material. The drying block is installed in the housing. The lid is hinged. The fan and heating elements are installed in the lower part between the walls of the case. Nozzles are installed on the inner walls of the housing. The drying block is made of disks arranged horizontally and at equal distance from each other with rings rigidly installed along the edge of their upper part. The nozzles are installed evenly over the disks along the inner surface of the body.

In FIG. 1 shows a general view of the device, and Fig. 2 - the same, section along A-A.

The device for drying fruits and vegetables includes a cylindrical body 1, a removable drying block, a control device 2, heating elements 3, a fan 4 and a cover 5. The body 1 is hollow and covered on the outside with a layer of heat-insulating material 6. The drying block is made of horizontal and at an equal distance from each other disks 7 with rings 8 rigidly installed along the edge of their upper part and installed in the housing 1. The cover 5 is hinged and forms a gap with the upper part of the housing 1 when closing. The fan 4 and the heating elements 3 are installed in the lower part between housing 1. In housing 1, air duct 9 is connected to fan 5, which, in turn, is connected to nozzles 10 installed on the inner walls of housing 1. Nozzles 10 are installed evenly above the disks along the inner surface of housing 1.

The device works as follows. The product to be dried is placed on the upper part of the disks 7 of the drying block, the layer of which should not exceed the edges of the upper part of the rings 8. Then the drying block is installed inside the housing 1. The drying block is closed with a hinged cover 5. Then, using the control means 2, turn on the fan 4 and heating elements 3 The heated air enters through the air duct 9 to the nozzles 10, from where it enters the upper part of the disks 7 of the drying unit. Then the heated air, blowing the upper part of the discs 7, evenly heats and dries the processed product located on them. By supplying heated air to each disk 7 of the drying unit and evenly distributing it over the upper part of the disks 7, the product to be dried is brought to a condition. The water vapor released during drying is removed outside through the gap formed by the cover 5 with the upper part of the housing 1. After drying is completed, the heating elements 3 are turned off using the control means 2, then the fan 4 is turned off and the cover 5 is opened. Then the drying block is removed from the housing 1, from where finished product.

Coating the casing on the outside with a layer of heat-insulating material reduces heat loss during drying. Making the body hollow, installing the drying block in the body, making the cover hinged, positioning the fan and heating elements in the lower part between the walls of the body, making nozzles on the inner walls of the body, making the drying block from disks arranged horizontally and at equal distances from each other with a rigid installation along the edge of their upper part of the rings, the installation of nozzles evenly above the disks along the inner surface of the body provides a uniform supply of heat to the processed product, increasing the quality of drying, as well as reducing heat loss.
