Detailed Description of the Embodiments
Features and principles of the present disclosure will be described in detail below in conjunction with the drawings, the embodiments are merely used for describing the present disclosure and are not intended to limit the scope of protection of the present disclosure.
According to a method for removing cyanide from stone fruit distilled liquor, the stone fruit distilled liquor is placed in a distillation still 1 for distillation, and steam in the distillation still passes through a packed column 2 and enters a condenser 3. Metal wires are distributed densely in the packed column, and the metal wires may be copper wires or other metal wires 23. After distillation, hydrocyanic acid in the steam of the distilled liquor enters the packed column, the hydrocyanic acid is neutralized by an oxide of the metal wires in the packed column to produce a stable metal complex containing cyanogen, the metal complex containing cyanogen adheres to surfaces of the metal wires, and the metal complex containing cyanogen is removed by regularly replacing the packed column or the metal wires in the packed column.
Further, the metal wires are copper wires, the hydrocyanic acid reacts with copper oxide to produce copper cyanide, the copper cyanide adheres to surfaces of the copper wires, and a reaction formula is that 8HCN+6CuO=4CuCN+2Cu(CN) 2+02 .
As shown in Fig. 1, Fig. 2 and Fig. 3, an apparatus for removing cyanide from stone fruit distilled liquor includes a distillation still 1, a packed column 2, a condenser 3, and communication pipes 4 therebetween. An unfinished stone fruit distilled liquor is placed in the distillation still, wherein specifically, the production process of the distilled liquor is the same as that of existing common fruit distilled liquor. The distillation still is connected to the packed column via the communication pipe, and the packed column is connected to the condenser via the communication pipe.
The packed column includes a cylindrical shell 21, wherein two ends of the shell are both provided with a copper sieve plate 22, each copper sieve plate is provided with sieve holes 24, and steam in the distillation still passes through the communication pipe and the sieve holes of the copper sieve, and enters the packed column. The shell and the copper sieve plates form a filling cavity, an outer side of each copper sieve plate is connected to the communication pipe, an inner side of each copper sieve plate is fixed with an edible round plastic pad that serves as a sealing pad, each copper sieve plate is fixedly connected to one end of each of a plurality of copper wires, and the other end of each copper wire is a free end, the free ends of the copper wires at two ends are inserted with each other to form a dense copper wire binding net. By increasing a contact area of the steam and the copper wire, a contact area of the hydrocyanic acid and the copper oxide is increased, thereby improving the adhering effect. After distillation, the steam in the distillation still enters the packed column and reacts with the metal oxide, wherein cyanogen is kept in the packed column, and steam without cyanogen enters the condenser and is condensed into distilled liquor.
Further, lengths of the copper wires at the two ends of the filling cavity are 1/2 of a length of the filling cavity, that is, the free ends of the copper wires at the two ends of the filling cavity are in contact, and if the packed column needs to be replaced or washed, only the cooper sieve plates together with the copper wires at the two ends of the shell need to be removed.
Further, two ends of each communication pipe are expansive clamping joints 5 for guaranteeing the tightness of the connection of the communication pipe, and diameters of the joints are equal to a diameter of the round plastic pad.
Hydrocyanic acid is neutralized by a metal oxide to produce a stable metal complex containing cyanogen, the metal complex containing cyanogen adheres to the surfaces of the metal wires, and the metal complex containing cyanogen is removed by regularly replacing the packed column or the metal wires in the packed column. The cyanide in the stone fruit distilled liquor is effectively removed without affecting the production of the steam of the stone fruit distilled liquor. The method can remove cyanide from stone fruit distilled liquor, enabling healthy production of stone fruit distilled liquor possible. In the process, only the metal wires need to be washed or replaced, so the method is convenient to use.
Apricot distilled liquor is taken as an example. Apricot fermented liquor with 12%vol alcohol content was used as base liquor, and distilled by using the present apparatus and a distillation apparatus without a packed column, respectively. The cyanide content in obtained distilled liquor was detected in accordance with an analytical method of cyanide of the National Standard of the People's Republic of China GB/T5009.48-2003 "Method for analysis of hygienic standard of distilled wines and mixed wines". Results were obtained by 100% alcohol conversion rate, as shown in Table 1: Table 1 Cyanide content in apricot distilled liquor
