Citrus peel, also known as orange peel, also known as orange peel, before the orange peel was mostly abandoned, but the nutritional value of citrus peel is quite rich. The orange peel is orange, flexible and sweet. It has a unique flavor and is loved by many people. Then, what kind of food processing equipment needs to be involved in turning citrus peel into waste?
What types of food processing equipment are needed for citrus peels?
Fruit peel
The common fruit peel is mostly made from hawthorn, and the citrus peel can be processed to produce fruit peels. According to the relevant personnel, to use moldless citrus peel, wash with clean water, drain, and then use a pulverizer. After crushing, the wetness is refined by a refiner, and it is usually milled 2-3 times to form a paste.
The citrus pulp is diluted with water, placed in a saucepan and concentrated, and then added with sugar, a small amount of citric acid to make it sweet and delicious. Then the citrus pulp is sent to the drying room for baking, the best temperature is about 65°C, baking time. Do not exceed 14 hours. After cooling, cut into long strips for packaging.
Concentration and baking steps are needed during the processing of the fruit peel. The concentration time of the citrus pulp needs to be strictly controlled, not too long or too short, too long time will make the slurry too viscous, too short, the slurry concentration is not high, Will affect the quality of the product. However, the market appears on the sandwich pot with electronic control box control, equipped with automatic temperature control system, heating temperature, time is easy to control. In addition, easy installation, easy operation, safe and reliable.
Orange peel
The author understands that the first step is to wash the citrus peels first. The purpose is to wash away the dirt and there are some pesticide residues. Then cut the orange peel into strips, you can choose the length according to the actual needs, and then soak it with 10% salt water 1 - 2 days, remove bitterness.
Put the orange peel into boiling water again. Do not boil it for too long or too short. Cook it thoroughly. Soak it in a sugar pan for 24 hours. Drain it, drain it, and put it in the oven. Baking in a drying room, the temperature is preferably about 66°C, and it is taken out at 80% dry.
According to industry sources, if industrialized production and processing of orange peel, it is best to use a pre-cooker to boil the orange peel, because the device is mainly used for blanching treatment of fruit and vegetable materials, and the temperature and time can be adjusted to ensure that the orange peel boiled Quality. In addition, it has the characteristics of fast fixation, enzyme protection and timely dehydration cooling, so that the fruits and vegetables to maintain the original natural color.
Orange peel powder
Actually, like orange peel and orange peel, in the production process of orange peel, it first needs to be cleaned to remove certain pesticide residues from the epidermis. After that, the washed orange peel is crushed by an ultrafine grinding device. Drying can be achieved by freezing into a spray, etc., to produce orange peel powder with good color and flavor. Orange peel powder can be used as a flavoring agent, colorant, and dietary fiber in pastries, cookies, and ice cream.
We know that the production of orange peel needs to go through many processes, and it is not ruled out that some of the impurities in the process will enter the orange peel powder, which will affect the purity of the material. Related personnel suggest that after spray drying, it is best to increase the screening process and pass through the sieve. Machine screening, according to the needs of the process can choose different equipment, to achieve efficient, accurate screening purposes.
Xiaobian epilogue: In fact, in addition to the above-mentioned by-products of processing, citrus peel can also be made into orange peel, orange peel, orange peel tea, orange peel pectin, orange peel extract, orange peel essential oil, etc., originally abandoned Orange peel, through the relevant processing technology and equipment, realized 'turning waste into treasure', improved the comprehensive utilization rate of orange peel, greatly enhanced the added value of citrus, and also promoted the development of regional citrus deep processing industry.
