Automatic Control Vacuum Frying Machine For Carrot Chips Making High Efficiency
- Vacuum frying VS deep frying VS hot air drying
Dehydration and drying is an important technology for processing many fresh agricultural products. It is of great significance for extending the shelf life of agricultural products, reducing the loss of decay, and increasing the added value of agricultural products.
1. Traditional hot air drying is the most commonly used technology in agricultural product processing, but hot air drying takes a long time, the product is easy to shrink, discolor, and the nutrient loss is large.
2. Deep-fried is a process in which oil is used as a heat transfer medium to combine food from surface to interior for thermal dehydration and cooking. It has high efficiency, low energy consumption, can give food with special texture and aroma, and high digestion and absorption rate. However, atmospheric pressure frying requires higher temperature (180 °C), the nutrients of food are damaged, color and fragrance. The taste is affected, and even some substances harmful to the human body are produced.
3. Vacuum frying technology puts the food under negative pressure and its absolute pressure is lower than atmospheric pressure. In this case of relative hypoxia, food processing can reduce or even avoid oxidation (such as fatty acid loss, enzymatic browning and Other oxidative deterioration, etc.).
Carrots contain sucrose, glucose and rich beta-carotene, which are loved by people. However, its method of consumption is limited, and most of it is used in conjunction with other vegetables. Emerging vacuum-fried casual snacks have changed the traditional way of eating carrots for many years, and vacuum frying technology has given people another insight into vegetables. At the same time, children who do not like to eat vegetables can get the nutrients they need through snacks.
Vacuum frying is a leading trend for the snack foods, it is a green revolution. Liuyi's vaccum fryer is made out within 20 years' experience.
- Carrot Chips Vacuum Frying Process
1. Process: fresh carrot → selection → cleaning → peeling → slicing → pre-cooking → dehydration → vacuum frying → de-oiling → cooling → weighing → packaging → finished product
2. Mechanical equipment: cleaning tank, peeling machine, slicer, sandwich pot, drying box, vacuum fryer, centrifuge, packaging machine
The carrot chips are put in a vacuum fryer for frying, the vacuum degree can be controlled at -0.098 MPa. The oil temperature is controlled at 80 to 85 ° C. And the frying time can be determined according to the carrot variety, texture, frying temperature and vacuum degree. Specifically, when the foam on the carrot piece disappears completely through the observation hole of the fryer, it indicates that the frying is over, and the oil content is below 35% to 40%. Centrifugal de-oiling removes excess oil from the carrots immediately after frying. If vacuum de-oiling is used, the oil content will be less than 20%, which makes it easier for consumers to accept and extend the shelf life.
