Abstract

FIELD: agriculture.

SUBSTANCE: device for drying bee bread honeycombs comprises a housing, an electric heater, air ducts, honeycomb shelves, a charging door, a drum formed as a cylinder mounted inside the housing with the ability of rotation and equipped with a reversible drive. The housing is designed as a vertically mounted cylinder with double walls and its outer surface is covered with a heat insulating material. Coaxially with the housing on the upper base of the cylinder a cover with holes is placed, on which the perforated plate is coaxially mounted with the ability of rotation about its axis. The shape and location of the holes of cover and the plate are identical. There is a gap between the inner wall of the housing and the cover. The lower base of the housing between the cylinder walls is made perforated.

EFFECT: device enables to reduce the energy consumption for drying bee bread honeycombs.

Description

The invention relates to agriculture, in particular, to devices for drying honeycomb honeycombs.

Known installation for drying the beers in honeycombs [Installation for drying the beers in honeycombs. - Patent RU 114135. - Publ. 03/10/2012, bull. No. 7], which includes a circular casing, an electric air heater, air ducts, shelves for honeycombs, a loading door. Inside the casing, the supports E are rotatably mounted with a drum E in the form of a cylinder. Shelves for honeycombs are made in the form of channels and are installed parallel to each other and symmetrically inside the drum on its upper and lower bases. The drum is equipped with a reversible drive.

The known device has disadvantages, which include high energy costs for drying and low productivity. The purpose of the invention is the reduction of energy costs for drying perga honeycombs.

This goal is achieved by the fact that the casing is made in the form of a vertically mounted cylinder with double walls, and its outer surface is covered with a heat insulating material. Coaxially with the casing, on the upper base of the cylinder, a cover with holes is installed. On the lid, coaxially with it, a perforated plate is mounted with the possibility of rotation about its axis, moreover, the shape and arrangement of the openings of the lid and the plate are the same. There is a gap between the inner wall of the casing and the cover, and the lower base of the casing between the walls of the cylinder is perforated.

Figure 1 shows a General view of the device, figure 2 is the same, a top view.

The device for drying honeycomb honeycomb consists of a casing 1, made in the form of a vertically mounted double-walled cylinder, having a loading door 2, an electric air heater 3 and an air duct 4. Inside the casing 1, on the supports 5 are rotatably mounted and equipped with a reversible drive 6, a drum 7 is made in the form of a cylinder. In the drum 7, shelves for honeycombs 8 are installed, which are made in the form of channels and are installed parallel to each other and symmetrically inside the drum 7 on its upper and lower bases. The outer surface of the casing 1 is covered with heat-insulating material 9. Coaxially with the casing 1, on the upper base of the cylinder, a cover 10 with holes is installed. A plate 11 with holes is mounted coaxially with it with a possibility of rotation about its axis and the holes of the cover 10 and the plate 11 are aligned with the holes. There is a gap between the inner wall of the casing 1 and the cover 10. The lower base of the casing 1 between the walls of the cylinder is perforated.

The device operates as follows. Through the loading door 2 on the shelves for honeycombs 8, honeycombs with a perga are installed. The plate 11 is rotated about its axis in such a way that the openings in it do not coincide with the openings in the cover 10. Then, by means of a reversible drive 6, the drum 7 is rotated. An electric air heater 3 is turned on, which supplies heated air through the duct 4 to the inside of the drum 7 The air washes the surface of the rotating honeycombs, taking away excess moisture from them. Further, air passes between the double walls of the casing 1, giving them part of the heat, and then through the perforated lower base of the casing 1 is removed to the outside. Periodically, the direction of rotation of the drum 7 is changed to more evenly blow both sides of the honeycomb.

When the ambient temperature is above 25 ⁰ C and its low humidity, the holes located in the cover 10 and the plate 11 are fully or partially combined, turning the plate 11 relative to the cover 10. In this case, the heating elements of the electric heater 3 do not turn on (or turn on periodically) to save electricity, providing a better quality pulse drying. In this case, the heat from the inner wall of the casing 1 is partially transferred to the fresh air entering the dryer, thereby reducing the cost of electricity for heating it.

The dried cells are removed through the loading door 2.

Due to the implementation of a circular casing with double walls and thermal insulation of its outer surface, heated air heats the plants faster to a predetermined temperature, reducing drying time. Under favorable weather conditions, the combination of the openings of the lid and the plate makes it possible to dry the cells only by convection of air without additional heating, reducing the energy consumption for drying.
