Description

DEVICE FOR BEE BREAD SEPARATION FROM THE HONEYCOMB

Technical field

The invention is attributed to agriculture, beekeeping branch, and can be specifically applied in the production of devices for bee bread separation from the honeycomb. Background Art

The main technological operations for bee bread separation from the honeycomb and processing include the process of crumbling honeycomb pieces containing bee bread, which is cut off the frame (for shaking bee bread from the comb cells) and the process of separation of bee bread pellets from wax (removal of wax and other impurities from bee bread pellets).

There is a known device for bee bread separation from the honeycomb consisting of a cyclone, an aspiration channel equipped with an air traffic controller, and a loading hopper mounted on the operating chamber, which is connected to the aspiration channel through the transition pipe. On the bottom of the loading hopper there is an adjustable discharge opening. There is a shaft inside the operating chamber, on a bearing support. Two working trowels and a wing are mounted on the shaft. Inside the operating chamber there are rifles in the shape of vertically arranged rods. The bottom of the working chamber consists of two parts, one of which has a shape of a plane with rifles, and the other is sieve-like (see RU patent No 2275800, AO IK 59/00, 2006).

Disadvantage of this device is that the structure is complex and cumbersome, threshing takes place in three areas, resulting in pellets losing their original hexagonal shape and being broken into smaller fractions, to the detriment of the product quality. The problem of the fraction separation is not solved in the unit, and the side and bottom edges, which are made of bars, are complicating the design, because a multitude of fissures that cannot be cleaned up between the rod and the wall, making it impossible to comply with the necessary hygiene requirements for the food industry.

The closest technical solution of the invention is the known device for bee bread separation from the honeycomb performing two technological operations - crushing pieces of honeycombs with bee bread, forming bee bread pellet and wax mixture, and separation of bee bread pellets from the crushed mixture. The device consists of a frame, a horizontal cylindrical rotary crusher, and an inclined sieve-type separator with an electric shaker and a spring suspension, an electric motor, a belt drive and a pull box. In the central part of the cylindrical cavity, the crusher is equipped with a rotor on two bearings. The rotor consists of a shaft and fingers attached to it, and which is coupled with a belt drive to an electric motor. Lower half of the cylinder is sieve-shaped, and the μρρεΓ half has a feeding opening with a vertical low wide chute for raw material supply, with large sloping walls, and the V-shaped row of teeth underneath. The crusher, the separator, and the pull box are arranged in the frame one under the other (see RU Patent 2367150, AO IK 59/00, 2009).

In this known device it is not possible to obtain high quality and higher yield of bee bread pellets, the device design is complex and bulky, not ensuring work safety for the operator feeding the raw material; frequent crusher cavity clogging; complicated cleaning of operating services of the equipment mechanisms which increases the loss of raw materials and operating costs of the device. These shortcomings are caused by the design of the device, because the centrifugal force ejects part of the raw materials (pieces of honeycomb with bee bread) and part of the crushed raw material mix, i.e. lightweight fraction particles, chute the wide and open feeding opening of the crusher with a vertical small feeding channel, which is widening towards the top, with high speed of the rotor, and the operator can injure fingers when pouring the raw material to the feeding chute of this design. Moreover, when pieces of honeycomb with bee bread are crushed between the V-shaped teeth and the rotating rotor fingers, part of the bee bread pellets are crushed and damaged, therefore the lightweight portion of finely divided bee bread is blown into the environment while the crushed mixture is running from the cylinder sieve, and when the crushed mixture yield is passed through the tremble separator, heavier part of the finely crushed bee bread passes through the sieve together with wax. Large wax fractions do not pass through the vibrating sieve and contaminate the product (bee bread) with wax.

Disclosure of the invention

The aim of the invention is to simplify the design and dimensions, increasing the bee bread pellet yield and quality, reducing operating _: costs and improving the operating staff safety.

The aim of the invention is achieved in that the unit for bee bread separation from the honeycomb, consisting of the crusher and the separator mounted in the frame, is interconnected with each other and to the motor with a belt drive, the crusher consists of cylindrical drum with the raw material inlet and the supply chute on top, and the outlet opening in the bottom part, with the levelling chute of the bee bread wax flow and the cleaning openings on the sides, with easily attached caps, in the middle of which the shaft is mounted on one axis. The shaft is connected to an electric motor with a belt drive, the separator consists of a centrifugal fan with a tilted plane located above the blow-off opening for bee bread-wax mixture spreading, and the airflow with a channel of bee bread-wax mix with deflector connecting the bee bread collection box, wax mix collection box, wax fraction mix collection box between which there is a separating edge, and a filter for separating fine wax fractions from the air, and the upper part, on the opposite side of the raw material inlet chute, is equipped with the chute for supply of dried bee bread for additional separation, directed towards the bee bread- wax flow levelling chute.

In addition, the raw material feed opening is in the upper part of the cylindrical drum, lengthwise the cylindrical drum, and is inclined at 20-60 degrees to the vertical axis, opposite to the shaft rotation direction, it's lower wall consists of two planes intersecting at an angle, where one of them, adjoining the cylinder, is tilted so as to make a greater than 90 degree angle with the tangential to the circle plotted by the flails tips, connecting to the connection line of the bottom wall and the drum.

Also, the opening for the discharge of the crushed bee bread-wax is in the bottom part of the cylindrical drum along the cylindrical drum and is tilted at 20-60 degrees in relation to vertical axis, towards the shaft rotation direction.

Also, the bottom edge of the crushed bee bread-wax levelling chute is above the wax mass spreading plain.

Also, the shaft has flails mounted perpendicular to the shaft and positioned over the entire length of the shaft in a spiral pattern every 120 degrees.

Also, the deflector of the channel for air flow with bee bread and wax mix is directed towards the wax mix box, and the filter for separating fine wax fractions from the air is made of three filtering planes, i.e. two side planes and one top plane, and two blind planes positioned against each other.

Brief Description of the Drawings

The invention is explained in the drawings.

Fig. 1 shows the principal scheme of the device. The device consists of a frame 1, inside of which there is a crusher, consisting of a shaft 2 with flails 3, a cylindrical drum 4, a raw material feed opening 5, a raw material feed chute 6, a bee bread-wax mix discharge opening 7, cleaning covers 8, 9, and bee bread-wax mass flow levelling chute 10, a motor with a belt drive 1 1 , a separator consisting of a centrifugal fan 12 with a tilted bee bread- wax mass spreading plane above the discharge opening 13, a bee bread collection box 14, a wax mix collection box 15, a bee bread and air flow separation edge 16 between them, a channel for air flow with wax and bee bread mix 17, an air flow deflector 18 for diverting air flow with wax mix to the collection box 15, a filter 19 for separation of small wax fractions from the airflow and consisting of three filtering planes, of which two are side planes 20, 21 and one top plane 22, and two blind planes 23, 24, positioned against each other, and the chute for the supply of dried bee bread for additional separation.

Realisation of invention

The device operates as follows.

Chilled honeycombs with bee bread are placed to the raw material feed chute 6, which is mounted at an angle of 20-60 degrees to the raw material feed opening 5, and by virtue of gravity they flow through the inlet 5 into the cylindrical drum 4, where combs are crushed with the shaft 2 with flails 3 mounted on it. The steady layout of flails 3 reduces the required drive torque unsteadiness, which enables to use and electric motor of lower power. The resulting bee bread and wax mix mass passes through the bee bread and wax mass discharge opening 7, which is in the bottom part of the cylindrical drum 4, and proceeds along the flow levelling chute 10 to its lower edge until it falls on the plane 13. On the plane 13, bee bread and wax mix mass spreads uniformly and drops to the discharge air flow of the fan 12. Wax mix, due to its lower density, is blown by the air flow in the channel 17 to the wax mix collection box 15. Heavier fractions remain in the box 14, lighter fractions are separated from the air flow in filter 19. Blind planes 23 and 24 assure more even distribution of airflow passing through the filtering planes. Bee bread, because of its relatively higher density, moves in the air flow in a descending trajectory and, hitting the edge 16, falls to the bee bread collection box 14. Dried bee bread is supplied for repeated separation after drying, and is poured through the additional separation chute 25. Industrial Applicability

Compared with the prototype, the new design of constructive elements is simpler, less bulky, it reduces the amount of damaged crushed bee bread pellets while increasing their yield, improving quality and reducing operational costs, as well as increasing the service staff safety.
