Processing method of nuts capable of being peeled by hand

Abstract

The invention discloses a processing method of nuts capable of being peeled by hand. The processing method comprises the following steps: screening nuts, cleaning and airing the screened nuts, and freezing the aired nuts at -20 to 4 DEG C for 2-6 hours; putting the frozen nuts into a vacuum pot, heating the nuts at the air pressure of 0.1-0.9MPa and the temperature of 80-600 DEG C, and simultaneously rotating the vacuum pot up and down at the rotation speed of 2r / min-43r / min for 3-60 minutes, wherein rotating shafts are arranged at the two ends of the pot body of the vacuum pot and the cross section of the pot body is round; charging the heated nuts into vacuum freeze drying equipment for performing quick freezing to enable the nutshells to crack at the air pressure of 1.3-13Pa for 10-30 minutes; charging the cracked nuts into a vacuum frying pot for performing air frying at 80-100 DEG C for 25-60 minutes; charging the fried nuts into a vacuum low-temperature drier for performing drying at the air pressure of 0.4-0.9MPa and the temperature of 110-150 DEG C for 30-90 minutes; and performing screening and packaging. Through the above mode, the processing method of nuts capable of being peeled by hand is realized through a vacuum low-temperature technique.

Description

Technical field [0001] The invention relates to the field of nut processing, in particular to a processing method for hand-peeling nuts. Background technique [0002] Nuts such as walnuts and macadamia nuts are popular snacks by the general public. However, due to the hard shell of this type of nut, it is difficult to open it when eating. It requires external force to open, which causes inconvenience to eating. At present, vise tools and tigers are more commonly used. Although the pliers tool is convenient to use, the nut is easily broken due to uneven force due to the design of the vise itself. Chinese patent CN201243609Y can solve the crushing problem of pecan nuts to a certain extent, but the problem of this patent is that the crushing machine is huge, the design is complicated, the production and maintenance cost is high, and the patented product does not break the shell of pecan nuts. Complete, so the patented product is difficult to promote; at the same time, the shell of ...

Chinese patent CN201243609Y can solve the crushing problem of hickory nuts to a certain extent, but the problem that this patent exists is that the crushing machine is huge, the design is complicated, the production and maintenance cost is high, and this patented product is not easy to crush the shell of hickory nuts. Complete, so the patented product is difficult to promote; at the same time, the shell of this kind of nuts is strong, and it is very difficult to taste the nuts during the processing process, which affects the taste
