Description

Food dryer

Technical Field

The invention relates to the field of drying devices, in particular to a food dryer.

Background

With the improvement of the living standard of people, more and more people raise pets, so that more and more pet foods are needed, and the requirements of people on the nutrition of the pet foods are higher and higher for the health consideration of the pets. The pet food is food specially provided for pets, and is high-grade animal food between human food and traditional livestock and poultry feed. The pet food contains six nutrient components such as water, protein, fat, crude ash, crude fiber, nitrogen substances and the like, can provide basic nutrient substances required by life guarantee, growth and health for various pets, and has the advantages of comprehensive nutrition, high digestibility, scientific formula, standard quality, convenience in feeding and use, capability of preventing certain diseases and the like.

The processing process of the pet food generally comprises the processes of mixing, stirring, forming, drying, packaging and the like, the moisture content of the pet food is still high after the pet food is formed, and the moisture content of the pet food is reduced to a specified range by drying treatment for convenient storage and packaging. At present, the drying process of pet food is that the formed pet food is usually placed in a tray, the tray is placed in a drying box, and the pet food is dried regularly by utilizing hot air in the drying box. But because pet food its position in the stoving incasement is relatively fixed at the dry in-process, and the hot-blast density of stoving incasement is less for the hot-blast meeting come-up of stoving incasement, and then the temperature that makes the stoving incasement top can be higher than the temperature of bottom, in the same stoving time, the pet food drying effect who is located stoving roof portion and bottom has great difference, causes the inhomogeneous problem of same batch pet food drying.

Disclosure of Invention

The invention aims to provide a food dryer to solve the problem of uneven drying of a drying device in the prior art when pet food is dried.
