Description

The invention relates to equipment for processing meat and fish semi-finished products. The main purpose of the device is the introduction of a suspension of brine, marinade and solid fraction, for example, from plant parts containing essential oils, into the tissues of a semi-finished product.

Known injector for meat IN-11 [https://www.meatidea.ru/novoe-oborudovanie/proizvodstvo-delicatesov/inectori/inektor-11], consisting of a head with needles connected to a pump and a brine mixer.

Known automatic injector "IPA-15, 22x2" for introducing brine into meat and fish [https://zavod-pt.ru/catalog/inektory/inektor_avtomaticheskiy_ipa_15_22kh2_1300kh550kh1680_mm_22_dvoinykh_igly/].

An injector for introducing an edible liquid filler, such as brine, into pieces of raw meat, containing means for feeding the filler into a plurality of vertically arranged needles, a liquid pump, feed valves and suction valves, a conveyor [RU 2412617 C2, A23L 1/318 (2006.01), 27.02 .2011].

The disadvantages of these devices are their lack of mobility and the impossibility of injecting solid fractions.

There is a known syringe for introducing liquid into a product containing a body, a handle attached to it, a pipeline connected to the body and intended for supplying liquid, a pointed tube made with an opening in the region of the sharpened end, connected to the body and designed to introduce liquid through an opening into product, a valve installed in the body, a spring-loaded trigger connected to the valve so that it can be opened when the trigger is pressed [RU 17754 U1, А23В 4/28 (2000.01), 27.04.2001].

The disadvantage of this device is the impossibility of injecting solid fractions.

The closest is the device [WO 2020131297 A1, A22C 17/00, A22C 9/00, A23B 4/00, 2018.12]. The injector includes a pistol-shaped body that houses a battery-powered motor for continuous delivery of fluid from a peristaltic pump. The injector also includes a fluid channel within the housing, through which fluid is pumped from the fluid reservoir to the meat injection needle.

The disadvantage of this device is the impossibility of injecting solid fractions.

The task of the proposed device is the possibility of introducing a suspension of brine, marinade and solid fraction into meat and fish semi-finished products, as well as increasing the efficiency of this device by increasing mobility.

A new technical result that can be obtained by implementing the invention is to expand the capabilities of the device.

The proposed technical solution is carried out due to the presence of an extruder that allows you to introduce suspensions from brine, marinade and solid fraction, for example, from plant parts containing essential oils. The technical result is provided by the presence in the design of the extruder, as a device with which it is possible to push high-viscosity material, pasty multi-dispersed systems. Pumps of different types (peristaltic, piston with valves, centrifugal) are used only for pumping liquids or gases that do not contain a solid fraction [Pipeline transport of concentrated slurries. A.E. Smoldyrev, Yu.K. Safonov, M .: Mashinostroenie, 1973. - 208 p.]. Self-priming centrifugal pumps used in IN-11 injectors provide nominal pressure only at high performance, and the presence of solid fractions in the brine will reduce its performance and will not allow the development of sufficient pressure required to push through the needle cavity. The peristaltic pump uses the principle of deformation of a flexible hose with a liquid, the presence of a solid fraction leads to rapid wear of the flexible hose, in addition, such pumps cannot develop high pressure. A piston pump with valves must not be used for pumping slurries, as solid particles in the slurry can block the normal operation of the valves.

The claimed device differs from the prototype in that the suspension is fed by means of an extruder. The device allows you to inject suspensions from brine, marinade and solid fraction, for example, from plant parts containing essential oils.

The operation of this device will be clear from the following description and drawing.

Figure 1 shows a general view of the device. The device consists of a housing 1 in the form of a pistol, a hopper 2 attached to the housing, the cavity of which communicates with the extruder 3. An electric motor 4 is connected to the screw of the extruder 3 through a gearbox 5. A hollow needle 6 is connected to the outlet of the extruder 3, containing at least one hole, the diameter of which, as well as the inner diameter of the hollow needle, is not less than the largest size of any of the particles of the solid fraction of the suspension from the hopper 2.With the help of wires (not shown), the power supply 7 is connected to the electric motor 4 through the switch 8.

The device works as follows. The hopper 2 is filled with a suspension for injection, a force is applied to the body 1 and the needle 6 is inserted into the semi-finished meat product, then the switch 8 is pressed. Electric energy from the power source 7 is supplied to the electric motor 4, the shaft of which rotates the parts of the gearbox 5, while the rotation frequency decreases and increases the torque for rotation of the screw of the extruder 3. Rotation of the screw of the extruder 3 directs the suspension into the cavity of the needle 6, from the holes of which the suspension enters the processed meat or fish semi-finished product.

This device allows you to inject suspensions from brine, marinade and solid fraction into meat and fish semi-finished products, as well as to ensure more efficient use of the device due to its mobility.
