Description

A pollution-free tea drying equipment

technical field

The utility model relates to the technical field of tea production equipment, in particular to a pollution-free tea drying equipment.

Background technique

Drying is an important process of tea production. Its main purpose is to remove all the water inside and outside the tea, and at the same time achieve the purpose of shaping the tea and resisting oxidation. Especially for flat tea such as Taiping Houkui, the drying process is more It is the key to ensure that it can finally achieve flat and straight.

In actual production, after the tea leaves are flattened and formed, they are dried in a dryer to finalize the shape; the existing better drying equipment is a wooden drawer-type oven, which is made of wooden boards as the outer frame, and the drying sieves are stacked on the outer frame Inside and below, there are often the following problems: First, the production efficiency is extremely low. Since the existing high-quality tea drying process is still mostly oven-style manual operation, it has been difficult to improve the processing and production efficiency; Secondly, the service life of traditional drying equipment is low, which leads to frequent maintenance and replacement, and the loss is extremely high. If calculated by 10,000 tea farmers, more than 10,000 cubic meters of wood will be cut down every year, and nearly 1,000 acres of forest will be destroyed. It will cost 3-4 Thousands of yuan are used to replace and repair equipment, which destroys ecological resources while developing the economy; how to develop a tea that can not only guarantee the high-quality demand of finished tea products, but also meet the high service life demand while improving its production efficiency Drying equipment is a technical problem to be solved in this field.

As a thermal power mechanical hot blast stove, it began to be widely used in my country in the late 1970s. It has become a replacement product for electric heat sources and traditional steam power heat sources in many industries. Through long-term production practice, people have realized that only by using hot air as the medium and carrier can the heat utilization rate and thermal work effect be greatly improved. Traditional electric heat sources and steam thermal power are often equipped with multiple circulating fans during the transportation process, so that they will eventually form hot air indirectly for drying or heating operations. This process obviously has many shortcomings such as a large amount of waste of energy, excessive auxiliary equipment, and complicated technological process. The bigger problem is that this kind of heat source is helpless for the kind of requirements that require higher temperature drying or baking operations. Most of the existing tea hot air stoves are too simple in structure and function, relatively rigid, and it is difficult to control the influence of hot air on tea leaves when the temperature cannot be predicted, so the rate of defective and scrap products is extremely high, which affects production.
