Study on tunnel vegetable hot air dehydration dryer

At present, dehydrated vegetables have formed a large market, and most areas in China are still artificially aired, which is difficult to meet the requirements of the international market.
Study on tunnel vegetable hot air dehydration dryer
Fruit and vegetable dehydration methods are divided into normal pressure and negative pressure according to pressure. Atmospheric hot air drying is still the most common method for vegetable dehydration, but there are various new drying methods (vacuum freeze drying, vacuum frying, nitrogen filling drying, sonic drying, heat pump drying, microwave drying technology, far infrared drying, decompression The development trend of drying, superheated steam drying, solar drying, vibrating fluidized bed drying, etc., has certain application, and the use of hot air dehydration principle to dry vegetables is more suitable for China's national conditions.

Comprehensive application of camellia seed oil

图片
The traditional production methods of camellia seed oil are mainly solvent extraction method and mechanical pressing method, but the oil yield of these two methods is not high, and the impurities in the oil are more. With the innovation of process technology, recent supercritical extraction method and aqueous phase enzymatic hydrolysis method have also been applied in the extraction of camellia seed oil. According to the quality requirements of different fields, the camellia seed oil needs to be further refined after extraction. The refining process generally needs to undergo degumming, deacidification, decolorization, deodorization and fractionation to achieve the required standard of camellia seed oil. Microwave drying machine Camellia seed oil can be further processed to obtain corresponding refined oil, medicinal oil and cosmetic grade camellia seed oil. By controlling the process parameters, camellia seed oil can be more widely used.  Comprehensive application of c...

Advances in research on the health effects of nuts and their oils (2)

2 prevention of cardiovascular disease Epidemiological studies have consistently shown a negative correlation between the frequent intake of nuts and the incidence of coronary heart disease (CHD).  Microwave drying machine A total of 21,454 US male physicians registered with the Institute of Health were selected for the survey and 17 years of follow-up investigation. After controlling for known cardiovascular factors and other eating habits, I found that eating nuts twice a week or more nuts (peanuts, walnuts, almonds) with little or no nuts, heart attack mortality and crown The overall mortality of heart disease decreased, with RRs of 0.53 and 0.70, respectively, and 95% confidence intervals were (0.30 to 0.92) and (0.50 to 0.98), respectively. The survey showed a negative correlation between nut oil and total mortality of coronary heart disease, mainly to reduce the risk of sudden death from heart disease.

Coconut oil: a new choice for controlling porcine pathogens

图片
Weaning is the most critical stage in piglet growth, separation from sows, mixed piglets in different litters, new living environments, and diets that are adjusted from liquid milk to solid feed. This series of stress reactions usually leads to the adoption of this series of stress responses. Reduced food intake, which in turn leads to short-term growth. Microwave drying machinery During weaning, the small intestine undergoes significant changes in histology and biochemistry, such as intestinal villus atrophy and crypt hyperplasia, which reduces the digestion and absorption capacity of the small intestine, which causes post-weaning diarrhea, affects the immune response, and changes The normal composition of the intestinal flora eventually leads to a decrease in body weight, and animals are more susceptible to pathogenic bacteria.
