Description

Continuous blood processing equipment

Technical field

The technical solution relates to a device for continuous processing of blood and blood fractions.

BACKGROUND OF THE INVENTION

The slaughter blood for feeding purposes is mainly processed by drying in drying facilities, namely blood meal, scrap or flakes, or the dried blood is mixed with other materials for various feed meal. Drying equipment for slaughterhouses has high purchase costs and high space requirements. They are profitable only at large capacity and can therefore only be operated in large slaughterhouses, from small slaughterhouses it is necessary to weigh blood. Moreover, blood drying is very energy intensive.

It is an object of the present invention to provide a continuous blood treatment device which operates on the basis of an alternative technology and substantially overcomes the disadvantages of known processing devices.

The essence of the technical solution

The object of the present invention is to provide a device for the continuous processing of blood and blood fractions consisting of a vessel equipped with a mixing device for admixing the sulfur reagent with mechanically liquefied blood to which a pump suction is connected in the discharge line of a mixing piece. for the application of the acid reagent to the blood, and the discharge line is connected to a device for weighing and embalming the resulting product, wherein an acid reagent supply line with a metering pump is connected to the mixing piece.

From the point of view of the chosen technology it is advantageous if the pump is designed as a gear pump with adjustable speed. It contributes to a better dispersion of the acidic agent if its entry into the mixing piece is made in the direction of the blood stream being processed. The discharge line is preferably made of glass, which allows the consistency and color of the product to be monitored. The vessel may be provided with a level meter and a device for automatically dispensing a sulfur reagent that is connected to the control device. The pump, the weighing and embalming device of the resulting product and the metering pump can be connected to a control device.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS The technical solution will be further elucidated by means of the drawing, in which Fig. 1 is a diagram of one embodiment of a device for the treatment of carcass blood;

Examples of technical solution

The device consists of a vessel 1 in which mechanically liquefied blood is collected via a conduit. The vessel is equipped with a mixing device 2 and a level meter. A suction port 3 of the gear pump 4 is connected to the vessel 1. In its discharge line 5, a mixing piece 6 is connected, into which the inlet line 7 from the metering pump 8 is connected. The pump 4 has variable speed, its discharge line 5 is made of glass. The mixing device 2 and the level meter are connected to a control device. The pump 4, the weighing and embalming device 9 and the metering pump 8 are also connected to the control device.

The mixing piece 6 in the embodiment according to FIG. 2 is formed by an elbow into which the supply line 5 flows in the direction of the blood flow to be treated. The control element is designated as 10 and the control valve plug is designated as.

Depending on the level in the container 1, the dosing device dispenses sodium bisulfite into the liquefied blood so that its concentration reaches 1% by weight. The movement of the mixer 2 will completely dissolve the sodium bisulfite in the blood. A pump 4 is then actuated which transports the blood through the discharge line 5 through the mixing piece 6 to the weighing device 9 for assembling the resulting product. In the mixing piece 6, 20% hydrochloric acid is injected into the blood stream in such a quantity that the pH of the resulting product is in the range of 2.7 ± 0.5. The acid is fed to the mixing piece 6 via a feed line 7 and is dosed by a metering pump 8. In the weighing and embalming apparatus 9, the slurry resulting product is filled into bags. Once the bag is filled, resp. To achieve the set weight in the bag, the pump 4 and the metering pump 8 stop automatically and the filled bag can be replaced with an empty bag. Kuželka JJ. the control valve is adjusted by the 1Ό control so that the acid supplied is perfectly mixed with the liquefied blood.
