Example Embodiment

[0017] Example 1

[0018] The present invention is realized in this way, and its process steps are:

[0019] (1) Raw material selection: remove defective products after harvesting fresh peanuts;

[0020] (2) Drying: drying in a dryer (40°C) for 5-6 hours, and drying until the moisture content is in the range of 21%-26%;

[0021] (3) Measuring moisture: measure the moisture of peanuts every 1h;

[0022] (4) Peeling: Peel the peanuts on the peeling machine;

[0023] (5) Drying: Dry the moisture of peanut kernels in a blast drying oven (41°C) to a safe moisture range of less than 10%;

[0024] (6) Freshness preservation: First prepare a compound preservative (0.25% chitosan, 1% calcium propionate, 0.02% β-carotene, 0.01% rosemary, the balance is sterile distilled water into the reactor and stir evenly, Get the required preservative), take 1000g of the prepared composite preservative and mix 2500g of peanut raw materials uniformly, take out the peanut raw materials, dry, and then add 2 packe...

Abstract

The invention belongs to the field of processing of agriculture products, and discloses a method for drying and storing fresh peanuts for reducing produced derogation at producing areas. The method comprises the following steps: putting the fresh peanuts into multilayer drying equipment, drying the fresh peanuts for 5-6 hours until the moisture content of the peanuts is reduced to 26-21%, rinding the dried peanuts, processing the peanut kernels with a fresh keeping agent, drying the processed peanut kernels once again, and inflating, sealing and packaging the dried peanut kernels for keeping fresh. The method disclosed by the invention has the positive effects that the fresh peanuts are dried by in sectional type drying manner, the fresh peanuts are vacuumized, inflated, sealed and stored, the drying time is short, phenomena that the peanuts are hot, moldy and the like caused by the peanuts are harvested on cloudy and rainy day can be avoided, the quality of the peanuts is guaranteed, and the method belongs to a green and safe physical technology; the processing technology is simple and easy to operate, and industrialization is easy to realize.

Description

technical field [0001] The invention belongs to the field of agricultural product processing and relates to a new technology for reducing and drying fresh flowers after production. Background technique [0002] During the peanut harvest period, if it encounters rainy days, the peanuts cannot be dried in time, and the peanuts are prone to mildew due to high moisture content, resulting in economic losses for growers and enterprises. If the harvest period of peanuts encounters cloudy and rainy days, mechanical drying is adopted, that is, segmental drying. First, the fresh peanuts are dried with a dryer to a certain moisture content, and then the shells are peeled on the sheller, and then the peanuts are dried on the blower dryer to In the safe moisture, vacuumize and fill carbon dioxide airtight packaging on a vacuum packaging machine, and store at room temperature. The use of segmented drying can guarantee the quality of peanuts under any weather conditions, and can avoid the...
