Embodiment 1

[0021] 1. Put 50-100g of shelled camellia seeds in the air for 10 minutes, and then put them into the material tray of vacuum microwave equipment and spread them evenly into a thin layer. The thickness of the thin layer depends on the size of the camellia seeds. In principle, Just lay a single seed on it; the initial moisture content of the camellia seed raw material will also affect the drying time and drying efficiency, so it is advisable to choose camellia seeds with similar maturity and shape that are picked in the same batch;

[0022] 2. Turn on the vacuum pump, adjust the vacuum degree, and control the vacuum degree at 0.05MPa;

[0023] 3. The choice of microwave power corresponds to the corresponding drying frequency by adjusting the power of 150W;

[0024] 4. Set the vacuum microwave time, select the time range of 10 minutes, and generally judge the reaction termination time according to the water content of camellia oleifera seeds;

[0025] 5. Due to the difference i...

Embodiment 2

[0027] 1. Put 50-100g of shelled camellia seeds in the air for 10 minutes, put them into the material tray of vacuum microwave equipment and spread them evenly into a thin layer. The thickness of the thin layer depends on the size of the camellia seeds. In principle, single The grains can be laid flat, and there are gaps between the grains. The initial moisture content of the camellia seed raw material will also affect the drying time and drying efficiency. Therefore, it is advisable to choose camellia seeds with similar maturity and shape that are picked in the same batch;

[0028] 2. Turn on the vacuum pump, adjust the vacuum degree, and control the vacuum degree at 0.08MPa;

[0029] 3. The choice of microwave power, by adjusting the power of 350W to correspond to the corresponding drying frequency;

[0030] 4. Set the vacuum microwave time, select the time range of 30 minutes, and generally judge the reaction termination time according to the water content of camellia oleif...

Embodiment 3

[0033] 1. Put 50-100g of shelled camellia seeds through ultrasonic treatment for 10 minutes, put them into the material tray of vacuum microwave equipment and spread them evenly into a thin layer. The thickness of the thin layer depends on the size of the camellia seeds. Just lay it, and there are gaps between the grains. The initial moisture content of the raw material of camellia oleifera seeds will also affect the drying time and drying efficiency. Therefore, it is advisable to choose camellia oleifera seeds with similar maturity and shape that are picked in the same batch;

[0034] 2. Turn on the vacuum pump, adjust the vacuum degree, control the vacuum degree at 0.1MPa, and gradually increase the vacuum degree from 0.08MPa to 0.1MPa, and 0.01MPa is an adjustment degree;

[0035] 3. The choice of microwave power, by adjusting the power of 500W to correspond to the corresponding drying frequency, the microwave power is gradually adjusted from 350W to 400W, and every 10W is a...

Abstract

The invention relates to the field of farm product processing, in particular to a drying technology of pregnant woman and wet nurse nutritional tea seed oil. The technical scheme of the invention is to provide a drying technology of pregnant woman and wet nurse nutritional tea seed oil. The drying technology comprises the following steps of: a, ultrasonically treating shelled tea seeds for 10 minutes, putting into a material tray of vacuum microwave equipment, and uniformly spreading; and b, drying the tea seeds with microwaves in vacuum, opening a vacuum pump, and controlling the vacuum degree at 0.05-0.1 MPa, wherein the vacuum microwave drying time is 10-60 minutes, the water content of the tea seeds is lower than 9 percent after vacuum microwave drying, and the tea seeds are overturned in the vacuum microwave drying process of the tea seeds. Due to the adoption of a method for drying tea seeds with microwaves in vacuum, the activity of functional components such as n-3 polyunsaturated fatty acids, vitamin E, oleic acid and the like in tea seeds are protected, the water content can be controlled below 9 percent, and raw materials are more stable and safer for storing.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a vacuum microwave drying method for camellia oleifera seeds. Background technique [0002] Camellia Oleifera Ahel is a unique woody oil plant in my country. It is mainly distributed in the mountains and hills of 14 provinces (regions) in the south of my country. At present, there are about 4 million hectares of Camellia oleifera forests in the country. The annual output of Camellia oleifera seeds exceeds 600,000 tons. Camellia oil extracted from Camellia oleifera seeds has high nutritional value and health care function, and its fatty acid composition is similar to that of olive oil, so it is called "Oriental olive oil". Tea oil contains tea polyphenols and camellia glycosides, rich in VE, VD, VK, carotene and squalene. Long-term consumption can enhance the elasticity and toughness of blood vessels, delay atherosclerosis, increase gastrointestinal absorption, and ...
