Almond kernel contains 2% ~ 10% sugar, 47% ~ 61% fat and 28% crude protein, and its crude protein content is higher than that of apricot (24.9%), walnut (15.4%) and sunflower seed (23.1%). It contains 2.9% ~ 5.0% inorganic salt, 0.17% ~ 0.60% tannin, 2.46% ~ 3.48% crude fiber. Almond contains 8 kinds of essential amino acids, which account for 28.3% of the total amino acids, higher than that of walnut and egg. Valine, phenylalanine, isoleucine and tryptophan in the eight essential amino acids contained in human body for proper functioning are higher than those in beef. In addition, almond kernel also rich in vitamin A, vitamin B1, vitamin B2, vitamin E, amygdalin, bitter amygdalin, digestive enzymes, and a variety of mineral elements and trace elements
The classification of shell peeling machine can be various, but can be generally divided into shell peeling machine and shelling, cleaning machine. Among them, the latter is more widely used. The almond shelling cleaning machine produced by Shuliy is a versatility machine having the function of husking and cleaning in one operation, which integrates the functions of almond husk and kernel separation. In general, the new almond husking shelling machine has the characteristics of simple structure, convenient operation, low power consumption and low noise.
The main devices of Shuliy’s almond shelling machine includes screen mesh, frame, fan, rotor, single-phase motor, (of two kinds of size), hopper, vibration sieve, and its transmission and other components of the triangle. The shelling effect can be carried on through repeated attack, friction, collision of rotor shell, after finished cleaning under the effect of rotating wind pressure, in which shells with light weight can be blown out of the shelling chamber, with kernels through screening of vibrating screen to achieve the purpose of separation.
