Tea seed drying machine and method

Abstract

The invention relates to a tea seed drying machine and method. The tea seed drying machine comprises a centrifugal fan, a heat exchanger, a drying box with an opening, a steam generator and a controlsystem used for controlling the wind power of the centrifugal fan; an air inlet is formed in the side wall of the drying box, and the heat dissipation surface of the heat exchanger is located betweenthe air outlet end of the centrifugal fan and the air inlet; the heat exchanger is communicated with the steam generator through a steam inlet pipe, and a sieve plate is arranged in the drying box; the sieve plate is in clearance fit with the bottom of the drying box, the gap forms a drying channel, and the air inlet is communicated with the drying channel. The tea seed drying machine and method have the advantages that tea seeds in the drying box are subjected to segmented drying treatment by utilizing the control system, so that by means of the design, the phenomena that the tea seeds in thedrying box are not heated unevenly in the drying process and burnt are avoided; the energy consumption of the centrifugal fan is reduced, the manufacturing cost of the tea seeds is reduced, and thenthe quality and mouth feel of finished tea oil products are also ensured.

Description

technical field [0001] The invention relates to the technical field of baking machinery and equipment, in particular to a tea seed dryer and a drying method thereof. Background technique [0002] Camellia oleifera seed is a unique woody oil plant in my country. It is widely distributed in southern China. Camellia oleifera oil extracted from camellia oleifera has high nutritional value and health care functions. It can enhance the elasticity and toughness of blood vessels, delay arteriosclerosis, and increase gastrointestinal absorption. , promote endocrine, prevent the decline of nerve function, improve human immunity, etc. Its fatty acid composition is similar to that of olive oil, and it is called oriental olive oil. Therefore, camellia oil has a great market space in our country. Drying is the first process in the processing and utilization of Camellia oleifera seeds, which has an important impact on the quality, oil yield and oil quality of Camellia oleifera seeds. For ...

AI Technical Summary

Problems solved by technology

For a long time, camellia oil has been mainly planted, collected and managed by farmers themselves, and pressed in workshops, and dried mainly by frying and drying in the sun, which takes a long time, is labor-intensive, and has a high moisture content. The seeds are easy to rot, and the oil is corrupted by acid, which seriously affects the subsequent processing and becomes one of the bottlenecks in the large-scale production of camellia oil

In addition, some enterprises also use dryers to dry camellia oleifera seeds. However, the existing dryers include a drying box. When drying the tea seeds in the drying box, parts of the drying box The tea seeds in the area are not evenly dried and heated, and even the tea seeds in some areas will be burnt and pasty, which will affect the quality and taste of the finished tea oil; and the overall structure of the dryer is complicated, and the manufacturing cost is high.
