Embodiment 1

[0018] The present invention is achieved like this, and its processing step is:

[0019] (1) Selection of raw materials: remove defective products after fresh peanuts are harvested;

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

[0021] (3) Moisture measurement: measure the moisture of peanuts every 1 hour;

[0022] (4) Shelling: Peanuts are shelled on the shelling machine;

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

[0024] (6) Preservation: first prepare the composite preservative (0.25% chitosan, 1% calcium propionate, 0.02% beta-carotene, 0.01% rosemary, the remainder is that aseptic distilled water is added in the reactor and stirred evenly, Promptly obtain required antistaling agent), get the compound antistaling agent 1000g that makes and mix evenly with 2500g peanut raw material, take out peanut raw material, d...

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...
