Description

An energy-saving aquatic product processing dryer

technical field

The utility model relates to the technical field of aquatic product processing, in particular to an energy-saving aquatic product processing dryer.

Background technique

At present, food dryers are widely used in the field of food processing, and their function is to remove moisture from food. For example, the Chinese utility model patent with the application number of 201320317790.7 discloses a dryer for seafood processing, which mainly includes a conveyor belt, a heating device and a drying cabinet. The heating device includes a steam boiler and a gas pipeline, and the steam boiler passes through The air duct transports the hot air into the dryer cabinet. It uses steam to provide heat source, which is environmentally friendly and can meet production requirements. However, during its use, a large amount of hot air will also be discharged from the air outlet, resulting in waste.

Contents of the invention

In order to achieve the above purpose, the technical solution adopted by the utility model is: an energy-saving aquatic product processing dryer, including a frame, a conveyor belt, a conveyor belt driving device, a heating device, and a drying box arranged in the middle of the frame , characterized in that: the heating device includes a steam boiler, a gas pipe and a first aeration pan arranged at the bottom of the drying box, and a preheating box is also provided on the front of the frame, and the preheating box is connected with the The upper part of the drying box is connected through the exhaust gas recovery pipe. There is also a blower on the exhaust gas recovery pipe. There is also a connecting pipe in the preheating box. The upper end of the connecting pipe is connected with the outlet of the exhaust gas recovery pipe. Two aeration discs.

Further, the outer walls of the drying box and the preheating box are provided with insulation layers; the side walls of the drying box and the preheating box are provided with observation windows.

The beneficial effect of the utility model is: the structure is simple, and the high-temperature tail gas can be further utilized by setting the preheating box, and the products that need to be dried can be preheated first, so that the products can be quickly dried after entering the drying box. Heat up, improve efficiency, save energy and protect the environment.
