Heating kettle

Abstract

The invention relates to a heating kettle which comprises a kettle body and is characterized in that the kettle body comprises an outer-layer kettle body and an inner-layer kettle body; a sealed interlayer cavity is formed between the outer-layer kettle body and the inner-layer kettle body; a plurality of heat conducting pipes which are arranged in a frame shape and are communicated with the interlayer cavity are arranged at the periphery of the bottom of the outer-layer kettle body; the inside space of the heat conducting pipes which are arranged in the frame shape forms a combustion chamber; a charging opening is arranged at the initial end of the combustion chamber, and a smoke discharging outlet is arranged corresponding to the tail end of the combustion chamber; each heat conducting pipe is communicated with the bottom of an expansion oil tank through an oil inlet pipe; and an oil outlet pipe is arranged at the upper end of the outer-layer kettle body and is used for communicating the interlayer cavity and the expansion oil tank. The kettle body of the invention has large heating area, uniform heating and high temperature-rising speed, thereby preventing materials in the kettle body from being brown partially and sticking on the kettle to prolong the service life of the kettle body. The invention has the advantages of high heat utilization ratio, high material cooking speed and fuel saving and is especially suitable for processing and cooking aquatic products such as fishes, shrimps and the like.

Description

technical field [0001] The invention relates to a pot for processing aquatic products, in particular to a heating pot suitable for processing cooked products of aquatic products such as fish and shrimp. Background technique [0002] We know that when making dried aquatic products such as dried fish and dried shrimp, they must first be cooked and dried in order to store them for a long time. At present, when fish, shrimp and other aquatic products are cooked, the heating pot used is an ordinary iron pot, and the pot body is placed above the combustion chamber. Fast, the temperature is not easy to control, the material in the pot is heated unevenly, the phenomenon of local material scorching and other parts of the material will appear in the heating part, and the burnt part will cause sticking to the pot, which will reduce the service life of the pot; in addition, Part of the heat generated by fuel combustion will escape from the periphery of the combustion chamber and the ex...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of uneven heating of the pot body in the prior art, difficulty in controlling the temperature, partial scorching of materials in the pot, reduction of service life due to sticking to the pot, and low heat utilization rate, the present invention provides a heating pot. Not only the structure is reasonable, the heating is uniform, the temperature is easy to control, the cooking speed of the material is fast, but also the heat utilization rate is high, and it overcomes the disadvantage that fish and shrimp are easy to stick to the pan, which improves the service life of the equipment
