Description

Dehumidification and preheating integrated device

Technical Field

Background

In the catering industry, the smoking oven is widely used, is mainly used for processing meat food and endows the meat food with unique smoking flavor, and is suitable for food processing modes such as smoking, steaming, drying, roasting and the like for meat products such as livestock, poultry, fish and the like and other food. Besides meat food processing, the smoking oven can also be used for baking eggs, dried beans, removing fruits and vegetables and the like, belongs to multifunctional and multipurpose equipment, and is suitable for multiple industries. The smoking furnace produces smoking through the smoke generator, and uniformly contacts with smoked food along with the circulation of air flow in the furnace to generate chemical and physical reactions, so that the food is endowed with special smoking flavor, and the smoking furnace has the functions of water removal, color development, sterilization, oxidation resistance and corrosion resistance. The existing smoking furnace does not properly treat the smoke, when the smoking furnace works, the smoke circularly has certain moisture in the furnace body, and at the moment, the smoking furnace does not have the function of properly treating the smoke with high-temperature and high-humidity gas and directly discharges the smoke under the action of a fan, so that the waste of resources is caused, namely, the smoke cannot be recycled after being treated in the smoking furnace, and the effects of energy conservation and emission reduction are achieved.

In the working process of the smoking oven, the humidity control in the oven is very important for food processing. The drying during the operation of the smoking oven is mainly divided into two cases, one is to form thin-film protein on the surface of the product to form a crisp skin to prevent the deep moisture from seeping outwards, and hot air is needed to dry the product in the case; the other is to leave the surface of the article moist and red, in which case cold air drying is required. Cold air drying is particularly suitable for the requirements of low-temperature fermentation and drying dehydration of food, such as fermented sausage, low-temperature air-dried food (salted fish, pickled fish), and air-dried food (pressed salted duck, sun-dried meat, bacon, salted meat, smoked fish, etc.). The smoking oven in the market often can not realize hot air drying or cold wind drying's selection in a smoking oven according to user's demand, and this two kinds of functions that just lead to the smoking oven in the market can not realize drying comprehensively have reduced the good use experience of user. For example, the relatively convenient automatically regulated smoking oven in market, patent number is: 201520091712.9, although the humidity inside the smoking oven can be automatically detected and adjusted, the heating and dehumidifying manner by the heating wire cannot meet the requirement of cold air drying for users.
