Description

The invention relates to the field of food industry, and more specifically to technologies for processing products of the baking industry, and can be used in the processing of returnable waste products of flour products, in particular finished briquettes of instant noodles.

A known method of producing biscuit crumbs from confectionery waste - from pieces (monoliths) of biscuit remaining after the formation of cakes for cakes. This method consists of grinding pieces of biscuit and their subsequent sifting (patent RU No. 2044487, CL A21C 15/00 12/15/1992). Due to various structural, mechanical and technological properties, this method cannot be used for high-quality processing of returnable waste of hard flour products, for example instant noodles.

Also known is a method of processing return waste products of flour products, including grinding, crushing and packaging (AS USSR No. 1355215, class A21C 15/00 04/30/1986). This method is mainly intended for grinding stale baking waste. When processing stale bread after grinding it, the latter is dried and passed through a heated shaft to a crusher, then it is sent to an extruder, after which the coated pan is covered with vegetable oil and icing sugar. Processed flour products, such as recyclable waste from instant noodles, differ in fat composition from stale bread. In this case, during the heating process as a result of melting and release of fat, the processed product becomes plastic and sticks to the walls and cutting elements of the grinder and crusher, which affects the quality of the finished product and can lead to malfunctions of the line.

A device for producing biscuit chips from confectionery waste is known. The device includes a cylindrical working chamber horizontally mounted on the bed with a rotor and a sieve and an electric drive, while the radial elements are rectangular blades, and the sieve is installed under the rotor at an equal distance from the blades with the formation of free space between the sieve and the blades with a height of 15-25 mm, moreover, the circumferential length of the sieve does not exceed 30 ° (patent RU No. 2044487, class A21C 15/00 12/15/1992). This technical solution is aimed at improving the quality of biscuit chips by mitigating the destructive effect of grinding elements on the structure of the biscuit and, due to various structural, mechanical and technological properties, cannot be used for processing return waste of hard flour products.

Also known is a line for the processing of returnable waste products of flour products, consisting of those installed during the technological process and interconnected by a conveyor of a grinder, crusher and packaging block (AS USSR No. 1355215, class A21C 15/00 04/30/1986). This line is intended mainly for grinding stale baking waste. In addition to the above-mentioned elements, the line contains a hopper for pieces, which is connected to the crusher by means of a heated shaft, which is unacceptable when grinding products containing fats, because in this case, during heating as a result of melting and release of fat, the processed product sticks to the walls and cutting elements of the grinder and crusher, which affects the quality of the finished chips and causes malfunctions of the line.

The closest in technical essence is the line for the processing of returnable waste products of flour products and the method that is implemented by this line, which is taken as a prototype (AS USSR No. 1355215, class A21C 15/00 04/30/1986).

The objective of this technical solution is to create a method and device that allows you to produce crumbs from the return waste of flour products containing a fat component, for example, instant noodles of high quality finished product.

This is achieved as follows. A method for processing recyclable waste products of flour products, for example, instant noodle briquettes containing a fat component, including grinding, crushing and packaging, involves preliminary crushing noodle briquettes into large pieces with their subsequent separation into two streams, each of which is fed to a corresponding disk knife mill, which operate alternately with a speed of rotation of circular knives of 3000-4000 rpm in intermittent mode for 1-2 s with an interval of 10 minutes, with constant monitoring Temperature, then the resulting litter is screened in two stages - on the sieve with a large mesh and on a sieve with a mesh size of 1.5 mm, after which the finished chips are packaged and packed, the crumb temperature at the outlet of mill selected not exceeding 30 degrees.

The technical result achieved also lies in the fact that the technological line for processing return waste products of flour products, for example instant noodles containing a fatty component, consisting of grinder, crusher and packing block connected along the conveyor conveyor, is supplemented by two mills and vibration sifter having two sieves, the first of which is made with a large mesh, and the mesh sizes of the second sieve do not exceed 1.5 mm, while the chopper is made a conical shape with horizontally mounted circular knives and is installed on each of the mills located between the crusher and the vibratory screener and having the ability to alternate work with an interval of 10 minutes, and the grinder of each of the mills is connected to the compressed air supply unit.

The proposed method for processing return waste products of flour products, for example briquettes of instant noodles containing a fat component, is as follows.

Return noodle briquettes with a violation in appearance, weight, shape, as well as sprinkling of briquettes arrive at the control position, where they visualize the appearance of the briquettes and reject the briquettes that cannot be processed. Next, the briquettes are pre-crushed into large pieces. Crushed crumbs are divided into two streams and fed alternately with an interval of 10 minutes to one of two circular knife mills, which operate alternately with a rotation speed of circular knives of 3000-4000 rpm in intermittently for 1-2 seconds. The alternate operation of the mills avoids the heating of the processed products and their adhesion to the knives and walls of the crusher and grinder, in addition, during the operation of the mills they are constantly cooled by a stream of compressed air. At the exit from the mills they control the temperature of the crumbs, which should be no more than 30 degrees. Next, the crushed briquettes are sieved in two stages, first on the first sieve with a large mesh, where large lumps of fat fraction are discarded, and then on a sieve with a mesh size of up to 1.5 mm. The crushed crumbs with a particle size of less than 1.5 mm and a temperature of not more than 30 degrees are packaged, packaged and labeled. This method can be implemented on a production line, which includes a crusher 2, interconnected by a belt conveyor 1, intended for preliminary grinding of returnable briquettes of noodles, a distributor 3 and two mills 4 and 5. The latter are installed parallel to each other and made with the possibility of alternating work at intervals 10 min, which eliminates the possibility of heating the processed products and their adhesion to the walls and cutting elements of the grinder and crusher. Each of the grinders 6 and 7 of the mills 4 and 5 is made conical in shape with horizontally mounted disk knives and connected to the unit 8 for supplying compressed air for cooling them. The execution of the cone-shaped grinder body reduces the fall rate of the processed product and, in combination with several horizontally mounted disk knives, reduces the fraction of the crushed product, i.e. improve the quality of the crumbs. After mills 4 and 5, a vibratory sifter 9 is installed, having two sieves 10 and 11, the first 10 of which are made with a large mesh, and the cell sizes of the second sieve 11 do not exceed 1.5 mm. The line also includes a reference home position 12 and a packaging unit 13 installed at the beginning and end of the line, respectively.

The claimed invention allows to expand the technological capabilities of the line by providing reliable and high-quality processing of returnable waste products of flour products containing a fat component.
