Description
Technical field
The present invention relates to baking and banking up with earth mechanical equipment technical field, especially a kind of furnace drying method of tea seed dryer.
Background technology
Tea seed is the distinctive woody oleiferous plants in China, and very wide in south China distribution, the tea oil extracted from oil tea has
Very high nutrition price and healthcare function, it can enhance blood vessel elasticity and toughness, delay artery sclerosis, increase stomach and absorb work(
Can, promote endocrine, prevention nervous function declines, improves the immunity of the human body, and aliphatic acid composition is similar to olive oil, there is east
The title of square olive oil.Therefore, tea oil has the very big market space in China.Drying is first of work of tea seed processing and utilization
Sequence has a major impact the quality of the quality of tea seed, oil yield and grease.For a long time, tea oil is mainly that peasant household plants, certainly certainly
It receives, from managing, carries out workshop-based oil expression, drying is mainly with fried dry method and natural suning method, and required time is long, and labor intensity is big,
The tea seed of high moisture content easily rots, and fatty acid corruption seriously affects following process process, becomes tea oil large-scale production
One of bottleneck.In addition, also there is Some Enterprises to be dried using dryer to tea seed, still, existing dryer includes
Drying box when being dried to the tea seed in drying box, causes the tea seed in the drying box inside points region to dry uneven heating
Even or even subregion tea seed can generate the situation of burnt paste, so as to influence the quality of finished product tea oil and mouthfeel；And it dries
The problems such as machine complicated integral structure, manufacture cost is higher.
Invention content
In view of the deficiencies of the prior art, the present invention intends to provide, one kind is simple in structure, manufacture is at low cost, right
Tea seed drying is heated evenly and tea seed will not be dried to coking, paste happens and ensures sample tea oil quality and mouthfeel
The furnace drying method of tea seed dryer.
The technical proposal of the invention is realized in this way：A kind of furnace drying method of tea seed dryer, it is characterised in that：Drying
