Drying method of a tea seed dryer

Abstract

The invention relates to a drying method of a tea seed drying machine. The drying machine comprises a centrifugal fan, a heat exchanger, a drying box, a steam generator and a control system, wherein an opening is formed in the drying box, the control system is used for controlling wind power of the centrifugal fan, an air inlet is formed in the side wall of the drying box, the cooling surface of the heat exchanger is located between the air outlet end of the centrifugal fan and the air inlet, the heat exchanger communicates with the steam generator through a steam inlet pipe, a sieve plate isarranged in the drying box, the sieve plate and the bottom of the drying box are arranged at an interval which forms a drying passage, and the air inlet communicates with the drying passage. The drying method has the advantages that tea seeds in the drying box are dried by sections by utilizing the control system, by adopting the design, the condition that the tea seeds in the drying box are not uniformly heated and are scorched and burnt in a drying process is avoided, energy consumption of the centrifugal fan is reduced, and the manufacturing cost of the tea seeds is reduced, so that the quality and mouthfeel of finished tea oil are guaranteed.

Description

technical field [0001] The invention relates to the technical field of baking machinery and equipment, in particular to a drying method for a tea seed dryer. 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 a long t...

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.
