Abstract

The utility model discloses a Low-level feeding drum type refrigerator, relating to a refrigerating installation. The utility model comprises a refrigerating chamber composed of heat-insulating layers, a low temperature rotating drum installed in the refrigerating chamber, a driving mechanism for the low temperature rotating drum, a scraper, a material feeding mechanism, a material discharging mechanism, a conveying pipeline communicated with a hollow shaft of the low temperature rotating drum for cryogen or secondary refrigerant, and a refrigerating mechanism. The position of the material feeding mechanism corresponds to any a section surface position of 110DGR circular arc section surface on the outer circumference surface of the low temperature rotating drum; the 110DGR circular arc section surface is drawn using a lower bus bar of the low temperature rotating drum as a starting point.

Description

Low level charging drum freezing device

The utility model relates to a kind of freezing equipment.

The feed entrance point of existing drum freezing device is all with respect in 30 ° more than the rotating cylinder side bus-60 ° of arc section faces, this high-order feeding manner is not only made troubles to operation, and it is often incompatible to multiple individual quick freezing product such as fillet, shrimp, fish, shellfish meat etc., can produce the unordered landing and the folded phenomenon of freezing of waiting to freeze product, be unfavorable for fully, effectively utilizing the area that freezes of rotating cylinder, so most producers have to select for use that floor space is big, efficient is lower, freeze the big straight line tunnel type steel band freezing plant of product drying loss.

The purpose of this utility model is: a kind of technical scheme of low level charging drum freezing device is provided, and this freezing plant feed entrance point is low, and favourable operation is applicable to the individual quick freezing product, generally can not produce the unordered landing and the folded phenomenon of freezing of waiting to freeze product.

The technical solution of the utility model is: low level charging drum freezing device, the refrigerating chamber that comprises thermal insulation layer 7 formations (is seen Fig. 1,2), be contained in the low temperature rotating cylinder 4 in the refrigerating chamber, low temperature rotating cylinder driving mechanism 6, scraper 3, feeding mechanism 1, discharging mechanism 2, the cold-producing medium or the refrigerating medium conveyance conduit 5 that are connected with the hollow shaft of low temperature rotating cylinder, refrigeration mechanism, the feed entrance point of feeding mechanism 1 is with respect to arbitrary section face position in 110 ° of arc section faces on the low temperature rotating cylinder outer circumference surface, these 110 ° of arc section faces are to be 110 ° of arc section faces that starting point is drawn on low temperature rotating cylinder outer circumference surface with low temperature rotating cylinder Down Highway, Down Highway 12 is through the vertical plane of low temperature rotating cylinder axial line and the line (see figure 2) that intersects with low temperature rotating cylinder bottom barrel, and refrigeration mechanism adds that by the cold-producing medium cooling cycle system or by the cold-producing medium cooling cycle system refrigerating medium cooling recirculation system forms.

The feed entrance point of feeding mechanism is with respect to arbitrary section face position in 90 ° of arc section faces on the low temperature rotating cylinder outer circumference surface, these 90 ° of arc section faces are to be 90 ° of arc section faces that starting point is drawn on low temperature rotating cylinder outer circumference surface with low temperature rotating cylinder Down Highway, and Down Highway 12 is through the vertical plane of low temperature rotating cylinder axial line and the line (see figure 3) that intersects with low temperature rotating cylinder bottom barrel.

Spacing between the conveyer belt of feeding mechanism and low temperature rotating cylinder outer circumference surface is less than or equal to thickness or the diameter of waiting to freeze product.The conveyer belt of feeding mechanism is flexible delivery band or elasticity conveyer belt.

Major advantage of the present utility model is: feed entrance point is low, be convenient to operation and include production line in, can adapt to multiple monomer fast food freezing processing such as fillet, shrimp, shellfish meat preferably, generally can not occur waiting to freeze the unordered landing of product and folding freezing phenomenon, help making full use of the area that freezes of rotating cylinder.
