Problems solved by technology

[0002] At present, raisins are mainly prepared by drying in the sun or in the shade, resulting in high sand and dust content in raisins, poor hygienic quality, and difficulty in meeting market requirements, which greatly affects the market competitiveness of raisins.
The main cleaning method of raisins is to use water to wash, and after cleaning, it needs to be heated and dried, resulting in high energy consumption and lower quality of raisins.
Especially the green raisins in the raisins are easy to brown in color after being washed and dried, and the quality and taste also change greatly. At the same time, the sugar content of the washed raisins seeps out, making the raisins stick to each other and difficult to disperse, making it impossible to carry out mechanical weighing. and packaging
In order to keep the raisins in a better loose state and surface quality, some processors oil the raisins, which will cause the raisins to oxidize and deteriorate during storage, resulting in odor
At the same time, cleaning with water as a solvent requires dehydration and high-temperature drying, which will also cause skin damage and browning of the raisins, and washing with water has no obvious effect on the eggs in the raisins.

Embodiment 1

[0029] Embodiment 1: A kind of waterless cleaning method of raisins

[0030] (1) After the raisins are screened, impurity removed, color sorted and graded, high-quality raisins raw materials are obtained, and the moisture content of the raisins is ≤30%.

[0031] (2) Sterilize the reactor, the preferred sterilization method is to use H 2 o 2 Disinfectant solution sterilization; after the reaction kettle is sterilized, put the raisin raw material into the filter basket and then put it into the reaction kettle.

[0032] (3) Introduce high-density carbon dioxide into the reactor for treatment. The treatment conditions are: temperature 20°C~50°C, pressure 5.8~50MPa, and keep it for 3~60min. While cleaning high-density carbon dioxide, ultrasonic treatment assists cleaning, frequency 10~60KHz, ultrasonic treatment time is 1~15min, after the treatment, release high-density carbon dioxide.

[0034] Embodiment 2: A kind of waterless cleaning method of raisins

[0035] (1) After the raisins are screened, impurity removed, color sorted and graded, high-quality raisins raw materials are obtained, and the moisture content of the raisins is ≤30%.

[0036] (2) Sterilize the reactor, the preferred sterilization method is to use H 2 o 2 Disinfectant solution sterilization; after the reaction kettle is sterilized, put the raisin raw material into the filter basket and then put it into the reaction kettle.

[0037] (3) Introduce high-density carbon dioxide into the reaction kettle for treatment. The treatment conditions are: temperature 20°C, pressure 5.8MPa, and keep for 60 minutes. While cleaning high-density carbon dioxide, ultrasonic treatment assists cleaning, frequency is 40KHz, ultrasonic treatment time It is 10min, and high-density carbon dioxide is released after the treatment.

Abstract

The invention discloses a waterless cleaning method for raisins, which uses high-density carbon dioxide combined with ultrasonic waves for comprehensive treatment, firstly cleans and sterilizes the reaction kettle with H2O2 disinfectant, and then puts the raisins into a filter basket and puts them into the reaction kettle; For high-density carbon dioxide treatment, the treatment temperature is 20℃~50℃, the treatment pressure is 5.8~50MPa, and it is kept for 3~60min; at the same time, ultrasonic treatment is used to assist cleaning, the frequency is 10~60KHz, and the ultrasonic treatment time is 1~15min. Adopting the present invention achieves the purpose of cleaning while also having the functions of sterilizing, killing insects and reducing pesticide residues. Using carbon dioxide as a cleaning solvent avoids the browning and sticking of raisins caused by water contact, and does not need to be dried after cleaning. The processing temperature is low, energy saving and environmental protection, so that the raisins maintain their original quality, color and loose state, and have a wide range of applications. Value.
