Embodiment 1

[0014] The collected fresh lotus powder (moisture content 28.5%) was placed in a freezer at -10°C for frozen storage, and the vacuum pulsation drying oven was started, and the drying temperature of the first stage was set to 52°C, and the drying time was set to 30 minutes; The stage drying temperature is set to 48°C, and the drying time is set to 30min; the third stage drying temperature is set to 44°C, and the drying time is set to 30min; the fourth stage drying temperature is set to 40°C, and the drying time is set to 60min. The vacuum degree of the drying chamber for vacuum pulsation drying was set between 0 and 0.093-0.094 MPa to pulsate at a pulsation ratio of 3min:9min. Spread the frozen lotus powder on the drying tray, the material thickness is 3mm; when the temperature of the drying room rises to the preset temperature of the first stage, the drying begins, and the weight of the tray containing the pollen is regularly measured and recorded until the material When the ...

Embodiment 2

[0017] The collected fresh tea pollen (moisture content 32.5%) was placed in a freezer at -10°C for frozen storage, and the vacuum pulsation drying oven was started, and the drying temperature of the first stage was set to 52°C, and the drying time was set to 20 minutes; The stage drying temperature is set to 48°C, and the drying time is set to 30min; the third stage drying temperature is set to 44°C, and the drying time is set to 40min; the fourth stage drying temperature is set to 40°C, and the drying time is set to 60min. The vacuum degree of the drying chamber for vacuum pulsation drying was set between 0 and 0.093-0.094 MPa to pulsate at a pulsation ratio of 2min:8min. Spread the frozen lotus powder on the drying tray, the thickness of the material is 2mm; start drying when the temperature of the drying room rises to the preset temperature of the first stage, measure the weight of the tray containing the pollen regularly, and record it until the material When the moistur...

Abstract

The invention discloses a method for dying bee pollens by utilizing pulsed vacuum, belonging to the technical field of food processing. The invention in particular relates to a processing technique of bee products in order to improve the drying rate of the bee pollens, reduce the drying energy consumption and improve the processing quality of the bee pollens. The method comprises the following steps: collecting fresh bee pollens, preliminarily removing impurities from the fresh bee pollens, then putting the fresh bee pollens in a sealed plastic bag and storing the fresh bee pollens in the environment at minus 5-minus 18 DEG C in a sealed manner after exhausting the air in the bag as far as possible; carrying out pulsed vacuum drying; and carrying out vacuum degassed packaging. The method has the following advantages: the bee pollen pulsed vacuum drying rate is higher than the traditional hot air drying rate; the energy consumption is reduced; and the colors of the bee pollens are bright and few functional components of the bee pollens are lost after the bee pollens are dried.

Description

technical field [0001] The invention relates to a low-temperature vacuum pulsation rapid drying method for bee pollen, which is suitable for the treatment of bee pollen before eating or processing, so as to reduce the water content of bee pollen, reduce the loss of functional components and the change of color during the drying process, and ensure the bee pollen The invention belongs to the technical field of food processing, and in particular relates to a drying method of bee products. Background technique [0002] Bee pollen is a natural health care product, which contains a variety of nutrients and functional ingredients necessary for the human body, and is known as "complete nutrition product" internationally. Studies have shown that bee pollen is rich in proteins, amino acids, carbohydrates, vitamins, lipids and other nutrients as well as enzymes, coenzymes, hormones, flavonoids, polypeptides, trace elements and other active substances, which can regulate metabolism, im...
