Description

TECHNICAL FIELD

[0001] The utility model relates to food processing equipment field, concretely relates to a double -deck hopper. BACKGROUND

[0002] Hopper is a collecting channel for conveniently collecting materials, which has a large opening at the top to easily receive the materials to be kept, and a narrow bottom end to distribute the materials in a controllable manner. In the food processing industry, the hopper is often arranged at the inlet and outlet of the processing production line. However, in the food processing process, there are cases where the temperature of the food needs to be rapidly changed or maintained. The existing solution is usually to extend the conveying belt of the food circulation and set up a heating room or a cooling room on the conveying belt. However, this solution occupies a large space and forces the extension of the food circulation time, which limits the production efficiency. Moreover, when both heating and rapid cooling are required in a process, a heating room and a cooling room need to be set up simultaneously, which results in low production efficiency and space utilization.

[0003] After searching, patent number: "CN203357865U" discloses "a hopper with cooling function", which includes an inner hopper, an outer hopper, and a connecting frame. The upper part of the inner hopper is a cylinder, and the bottom of the cylinder is shaped with a tapered discharge port. The bottom of the outer hopper is sealed and welded to the outer wall of the discharge port. The connecting frame is sealed and welded to the top of the inner hopper and the outer hopper on both sides. The inner hopper and the outer hopper form a sealed partition layer, which is filled with cooling water. The cooling water inlet and outlet are welded to the top and bottom of the outer hopper, respectively. The cooling effect is achieved by the contact between the cooling water in the sealed partition layer of the hopper and the materials in the hopper. However, the hopper is not a container, and the materials stay in the hopper for a very limited time. Therefore, the cooling effect brought by the contact heat exchange is also very limited.

[0004] Therefore, there is an urgent need to design a hopper that can stably and effectively maintain the temperature and rapidly cool down. UTILITY MODEL CONTENT
