PROCEDURE AND EQUIPMENT FOR THE

OBTAINING THE PROTEIN P.H.D. FROM THE

BLOOD OF ABASTO ANIMALS

DESCRIPTION

Procedure and equipment for obtaining the protein P.H.D. from the blood of slaughter animals.

OBJECT OF THE INVENTION

The present specification defines a procedure and the equipment required to obtain the Hydrolyzed and Discolored Protein of the Blood P.H.D. from the blood of food animals. For this, an integral industrial treatment of said blood is carried out from the point of collection and storage until obtaining said protein with optimum levels of quality by means of a series of stages that require a reduced number of elements and equipment that make the present procedure increases the production with respect to existing processes and at the same time allows the production costs to be much lower.

The purpose of this invention is to be applied within the industry of treatment of biological elements and in particular in the industrial sector of equipments and treatment of blood coming from slaughter centers of slaughter animals for their later use.

BACKGROUND

It is known in the industrial sector related to the use of blood from animals the problem existing in the different steps of its treatment. For example, the problem of achieving stability, sterility, and preservation of blood at the collection point arises; In the treatment of sterility it should be noted that the blood is susceptible to being contaminated with certain speed, for which currently stabilizing products are needed to protect for a time without determining said blood against contaminants, mainly during transport and storage; or the drawbacks related to discoloration, since the strong and persistent pigmentation of the blood makes the final product difficult to use as an additive and therefore hinders its commercialization. In this sense, the present invention defines an industrial process that improves the systems of conventional treatments consisting of a system of continuous collection of blood in the slaughterhouse, and the use of a hydrolyzing reactor and a decantation system, all in ambient temperature conditions without the use of cold or heat.

In contrast to these conventional systems, other methodologies are known which improve said treatment, as defined in the registration ES8308478 which discloses a method of treating blood and other liquid products in which the blood is treated with anticoagulant that retards coagulation, a composed of sulfur and oxygen, and a carbohydrate; or as defined in the registration ES2154182 which discloses a procedure for the recovery and purification of blood from industrial slaughterhouses, especially globine, for which physical-chemical extraction, precipitation and separation, in which mainly the addition of the aqueous solution of hemoglobin on acetone is highlighted in such a way that precipitation of the globin occurs. It is possible to emphasize that the present invention differs from this type of treatments in that it incorporates a differentiated physical-chemical treatment and in that it incorporates different stages of treatment in the collection and reception, separation, filtration, pasteurization, drying and final grinding to obtain of the PHD protein in optimal conditions for later use.

Also highlighted is the record ES2289937 that differs from previously defined procedures and incorporates stages of blood treatment from collection to final drying, but which is based on the separation of blood in both hemoglobin and plasma, and after the separation of the blood requires at least one reactor for the plasma, and another reactor for the treatment of hemoglobin, that is, a minimum of two reactors, and is also based on a differential treatment until obtaining the PHD protein, in all cases being open reactors. The present invention differs from said methodology in that it does not require the separation of the blood, does not require different open reactors, but needs a single closed and hermetic main reactor, and therefore the rest of the steps of the procedure differ from the methodology defined in that previous record, as for example in the processes of filtering, hydrolyzing, discoloration and dehydration; and the present invention incorporates an automation in all steps of the process. It should also be noted that the methodology of registration ES2289937 has the problem that due to the high number of reactors makes the cost that is required to make a lot is very high since there are many hours, in particular, to complete a batch since it is loaded until the end of the same, must pass a total of about 30 hours, an excessive time that reduces profitability. The present invention reduces the number of necessary equipment and reactors, thereby reducing the investment cost, as well as reducing the time necessary to obtain a batch of product, for which less than half of the product is required. previous antecedent's time.

It is for all of this that it is considered that the present invention, which is described in detail below, constitutes an innovative solution that differs from the equipment and steps of any type of blood treatment methodology of animals up to the known date and presents a solution with the PHD protein is obtained with optimal results for later use, there is an increase in production considerably by reducing process times, production costs are much lower, the necessary economic investment in machinery is reduced and the corresponding amortizations, reduce the risks of contamination when going through a closed and hermetic circuit; the hydric environmental pollution is reduced at the level of the slaughterhouses by giving an advantage to the blood that it does not have now; a raw material of high nutritive power and high digestibility is obtained for both people and animals; and the consumption of water for the process is reduced, which is a significant improvement from an environmental point of view.

Description of the invention

The present invention defines a method for obtaining the protein P.H.D. from the blood of slaughter animals, which is an automated procedure and which is composed of the stages that are defined below.

Prior to the definition of the procedure, it is stated that the present invention defines stages that require special equipment that can be located at any location. That is, these equipment for the development of the procedure can be located in the same industrial plant or slaughterhouse, or they can be located in a centralized way at a point or location that requires the transport of blood by tankers or remote pumping by conductions. In any case, the blood of the animals to be treated requires stabilization with conventional reagents.

Additionally, it should be noted that the procedure is automated, for which everything is controlled by a program that manages the production plant, and that has a series of pre-set parameters for the correct operation of the procedure. In this sense it must be taken into account that the program regulates the entry or addition in the reactor of the amount of stabilized blood from the slaughterhouse; water, whose quantity is proportional to the entry of blood; dilute hydrochloric acid; sodium hydroxide; and hydrogen peroxide or hydrogen peroxide; Likewise, there are detectors of the free oxygen, sulfite and pH content in the reactor. At this point it is again emphasized that the reactor is closed and hermetic, which is novel in any type of blood treatment.

Once the blood is stabilized and ready to be treated, the rest of the steps required to obtain the protein P.H.D. They are the following:

- Storage in an initial deposit of the blood obtained in the industrial plant or animal slaughterhouse.

- A fixed amount of stabilized blood is loaded in the reactor from the initial tank. This reactor has the particularity of being closed and being airtight. The charge of the reactor from the initial tank is carried out by a connection pipe with a peristaltic pump.

The entrance of blood into the reactor by the action of the peristaltic pump is slow, so that the liquid slides on the vertical walls to prevent foam from forming or the pump delivering the blood in the lower part of the ferrule together with anti-return valve.

- Once the amount of blood stabilized with the reagent has been incorporated from the slaughterhouse, the same amount of water is added to the reactor, using the same system as for the blood, that is, it slides along the vertical walls of the reactor. avoid foaming or the lower part of the reactor.

- Once the incorporation of the same amount of water and blood in the reactor has been completed, the agitation blades of the reactor are activated and the mixing of the mixture begins at low power and slow speed, maximum 15 Hz, to achieve uniformity of the liquid without the formation of foam. At this point it is emphasized that the important thing about the mixture of blood and water is that foams do not form, being really indifferent that water is introduced before the blood, or vice versa. The important thing is that it is not necessary to previously separate the blood in hemoglobin and plasma, but in the reactor itself the water dilutes the hemoglobin membrane and the protoplasm is released.

- Without stopping the movement of the agitation blades, a dilute hydrochloric acid addition pump adds said acid until reaching an acid pH point in which the entire mass coagulates, at which point the addition of acid is automatically stopped hydrochloric but the agitation continues.

- The agitation blades continue to work and, then, a sodium hydroxide addition pump , slowly begins to incorporate this alkali until a less acid pH is reached, corresponding to the moment when the coagulated mass loses its high viscosity to move to a liquid state .

- Once this pH level is reached, the movement of the stirring blades is stopped for a short period to make sure that said pH value remains stable and does not have alterations that destabilize the concentration of hydrogenions. The pH measurement is carried out by means of a pH meter that reaches the bottom, which is where the mixture is located.

- Checking the stability of the mass, a pump for the application of hydrogen peroxide or hydrogen peroxide, adds this component to the top of the mass of the reactors to begin its discoloration work. This addition is carried out with the stirring blades stopped.

- After a long period of time counted from the first addition of hydrogen peroxide, the same amount of oxygenated water is incorporated again with the same system and methodology. In this way the installation is maintained in the waiting phase and in which only the oxidative action of oxygen on the hemoglobin of the blood and the variation of the pH of the reactor content can be observed, all monitored by the reactor detectors.

- After a few hours have elapsed since the oxidation starts, and in view of the data indicated in the detectors, a series of calculations are carried out to carry out the precise modifications to achieve maximum effectiveness in the discoloration and for this the pH is modified with the addition of hydrochloric acid and / or hydrogen peroxide, to create optimal working conditions.

- Once the time passes, the pH is neutralized. To achieve neutralization, the team adds these components and starts and stops the agitation blades only to stabilize and neutralize the mixture as many times as necessary, until the time the pH stabilizes at the point where it is needed. has left after the last neutralization. In turn, the mixture is neutralized little by little because each time the pH value is raised the oxygen work is put into operation, until it reaches a pH value of the environment of 7.

- Next, a colloid mill is put into operation, whose function is to make the colloid smaller so that the oxygen works more and the neutralization process takes hold and so that no lumps are produced. The process of driving the colloid mill is such that it opens the discharge mouth of the reactor and starts a mono pump that extracts product from the reactor, enters it in the entrance mouth of the colloidal mill, the colloidal mill acts on the mixture, and this one conducts it again by means of conduits to the interior of the reactor generating a closed circuit.

- After a few minutes of recirculating the mixture, the system calculates the pH values in the reactor and adds sodium hydroxide to correct the acidity that the product may have.

- When it is considered that the content of the reactor is a yellowish mass, with a micronized appearance, a bypass valve is opened so that the product is conducted to a lung reservoir operating the agitation blades. In the same way, when the reactor is empty, the remains of the product, which are recovered together with those of the pipes and the colloid mill, are dragged and taken to the lung tank so that the entire mixture is in said tank. lung deposit.

- After the emptying, the reactor agitator is stopped, while the pump and the colloid mill are in operation. With a mains water hose, the reactor is internally washed, so in the same operation, all the hydrolyzed particles are carried to the lung tank. Next, the discharge opening of the reactor is closed, so that the interior of the reactor is subsequently flushed under pressure to eliminate any residue of solid matter that may have remained adhered to the walls. The washing waters, along with other resulting from the process, are conducted to a storage tank to subject them to a water recovery action. Once the cleaning operation has been completed, a pneumatic activator closes the discharge opening of the reactor, thereby terminating the hydrolysis and discoloration phase, the previous stages can be restarted again in order to load another new reactor with new raw material or stabilized blood from the industrial slaughterhouse of slaughter animals.

- Once the blood has been subjected to the phase of hydrolysis and discoloration, the resulting product in the form of a suspension of solid and liquid, which is in the lung reservoir shaking, is still treated since it must still oxidize the possible bisulfite that remains in the blood.

- When the product is stabilized, the lung tank transmits a signal and the following steps are started:

* first a low speed centrifugal filter pump is charged so that the solid is retained while the water is ejected. The maximum level of solids retained in the basket of the centrifugal filter pump is decided by a thickness gauge and when the maximum amount of cake has been achieved, said pump stops injecting hydrolyzate, and then water is injected for washing . It is followed with the introduction of network water to extract and wash the contents until the salt detector indicates that it has been possible to eliminate said salts. At that moment the entrance of the washing water stops and the centrifugal filter pump is automatically accelerated until it ceases to expel water;

* then the revolutions of the centrifugal filter pump descend to the discharge level and, then, a hydraulic knife descends inside the basket to detach the product or compact cake, which falls into a hopper that is located at the bottom of the basket. the centrifugal filter pump; Y

* Finally, an endless extraction collects the drained cake and moves it to a hopper designed to feed the dryer.

- The dryer receives the wet cake, which dehydrates in a regular and continuous manner.

- Once this drying process has started and after verifying that the humidity of the final product is adequate, 6% - 7% humidity maximum, and that the temperature does not exceed 40 ° C, the product is sent to a feed hopper of the micronized mill where it is subjected to grinding and cooling.

- The product or P.H.D. Dehydrated and milled is collected at the outlet of a pneumatic cyclone and packed there under conditions that guarantee its perfect preservation in suitable containers.

An analysis of the final product obtained shows us values of:

This is a slightly yellowish product with a semolina-like appearance of loose texture, just as the achieved aminogram is excellent in general, since tryptophan is not found to be a hydrolyzed product, and a molecular weight of the protein P.H.S. about 366.50 Dalton.

The special and innovative equipment required for the development of the methodology previously described, and that in certain points has already been advanced, is:

1.- A special reactor.

It is a closed and hermetic reactor, for the control of oxygen and the rest of variables, preferably made of steel. The capacity is at least four times the volume of blood to be treated.

Said reactor has a closed inlet mouth, an anchor-type agitator at the bottom with prolonged ends upwards and inclined blades perpendicular to the axis and distributed in its height. The reduction motor has a frequency converter for power regulation, preferably 30 r.p.m. and about 5 CV every 1,000 1 of blood. The shaft has a diameter preferably between 70mm and 100mm.

On the other hand, in the upper cover, since the reactor is closed, it has a PH meter or pH meter, a nozzle for the acid inlet, a nozzle for the alkali inlet and a nozzle for the incorporation of oxygenated water.

In the lower part it has an inlet for the blood load with anti-return valve, a peephole in the ferrule to see the state of the product in reaction, an entrance mouth on top of the ferrule with curve and tube discharge of the colloidal mill in the inner part of the reaction mass. It also has a lower discharge nozzle, a mono-type pump, and then a by-pass pump for the product to go to the colloid mill or to the reservoir that receives, maintains or feeds the centrifugal filter pump.

- An adjustable colloidal mill

As mentioned in the development of the methodology, the phase of neutralization of the mixture undoes the mass of blood and, the final result? It is a manipulable product, of a blackish color with coarse particles. This product and its granulometry, once the critical pH of precipitation has been regulated, the oxygenated water is added for its discoloration, and it can be observed that there are many fine bleached particles, while the coarser ones stand out for a dark color that is expensive to lose .

To solve this problem, a colloidal mill with metallic strawberries located at a controlled separation is used, which receives the product extracted from the pressure reactor. As a consequence of the friction between the milling cutters, this mill reduces the particles to a particle size of less than 200 p.

In the closed circuit generated from reactor to mill and reactor again, after a short time, the whole genus is homogenized to a minimum particle size that oxygenated water oxidizes and totally discolours with great ease.

The final product is yellowish in impalpable powder, and is referred to as P.H.D. Discolored Hydrolyzed Protein.

- A lung deposit.

Another equipment that facilitates the acceleration of the manufacturing process is the installation of a lung tank that, provided with agitation blades of low revolutions, which allows to maintain a perfect suspension of the hydrolysed and bleached product, as well as possible pH corrections. This tank has a mono pump with a frequency inverter, which regulates the ideal flow rate to the centrifugal filter pump.

In this way, while the operation of filtering and dehydrating the mixture is carried out, the production of a new batch in the hydrolysis and oxidation reactor can begin, having remained empty and clean. With this it is possible to obtain a higher production and a lower cost per kg of commercial final product obtained is achieved.

Computer control of the process.

All the equipment is controlled and monitored by a computer control, whose main control is focused on the reactor.

There is a series of control equipment that assess the data that is being produced, and transmit it to 4/20 mV to the computer center that controls the manufacturing process.

Different load cells are available, which are used to control the amount of ingredients that are introduced into the reactor to start the transformation process.

There is also a pH measuring electrode that is immersed in the liquid mass of the reactor, and sends the obtained pH and temperature data to the transmitter of the equipment that shows them on a control screen.

There is also an oxygen analyzer, which is another electrode that continuously measures the amount of free oxygen that is dispersed in the liquid mass and the measured data, as in the case of the pH meter, sends them to the transmitter that shows them in the control screen.

A sulfite detector is available, which is continuously indicating how the content of these is decreasing as the reaction hours pass.

Additionally there is a control of the water expelled by the centrifugal filter pump, which consists of a probe that transmits micro Siemens values of the salt content of the water resulting from the washing phase, so that the washing of the cake is with the water pure

Loading cells and an additional pH meter are available in the lung reservoir.

Finally, a computer program or software is available, which is inserted into the hard disk of the computer that controls the production plant, and which has a series of parameters that can be varied by the person authorized to access them, such as the quantity of blood to be loaded in a reactor, the amount of water to be added proportionally to the input blood or the amount of hydrogen peroxide to be added

Finally, and from a point of environmental point of view, it is important to highlight the water consumption used during the procedure. In particular, it can be said that net water is used, which is both mixed with the stabilized blood from the slaughterhouse itself and with the different reagents previously described in the different stages of the process. Initially water is included in the reactor, hydrolysis occurs, then discoloration, the colloidal phase of recirculation and pH stabilization is reached, for a subsequent transfer and washing and filtering. At this time, dehydration, micronization and packaging take place on the one hand, while on the other hand waste water is produced after filtering and washing, said waste water being passed through a column of activated carbon and an osmosis plant, producing brine on the one hand, and the water is taken to an evaporator with which evaporated water is produced but also reusable water is obtained again in the whole process. As an example, a slaughterhouse that collects about 5,000 1 / day of blood requires 5,000 1 of water for the reaction; about 250 1 of water to dilute acids; 250 1 of water to dilute alkalis; 250 1 of water to dilute oxygenated water; and about 7,000 1 of water for PHD washing; being a total of about 12.7501. They have to add about 4,0001 of water contributed by the blood and about 950 1 of water to evaporate in the drying, which makes a total of water that reaches the sewage treatment plant of 16,750 1. The salt content in these 16,750 1 of water to purify has about 190 kgs of sodium chloride and 90 kgs of sodium sulphate, that is, a total of sodium salts of 280 kgs. These 16,750 1 of treated water treated in a reverse osmosis plant produce water until the rejected brines have a concentration of 35 g / l, which is equivalent to recover daily as pure water, osmotized, without salts or other waste, some 8.750 1 to add to the head of the plant. The rest, 8,000 1 that contain a concentration of 35 grs / 1 can dehydrate and recover water if necessary and get 280 kgs of sodium salts that, dehydrated, can be compressed into blocks to make available in extensive ruminant herds . After this analysis, it can be seen that this procedure is very favorable from an environmental point of view.

To complete the description that is being made and in order to help a better understanding of the characteristics of the invention, an assembly of drawings is included as an integral part of the same, in which the following has been represented with an illustrative and non-limiting character:

Figure 1 is a representation of the different equipment that allows obtaining the final product.

Figure 2 is a representation of the water cycle with the different phases and equipment of the process.

Description of the drawings

In Figure 1 it is possible to observe the representation of the different equipment with which it is allowed to develop the different steps, stages and phases of the procedure object of the invention. Specifically, and following the stages of the description, it can be observed that:

- The stabilized blood (S) obtained in the industrial plant or animal slaughterhouse is stored in the initial deposit (1).

- The amount of stabilized blood (S) of the initial deposit (1) is charged to the reactor (3). The blood charge (S) is carried out by means of a connection pipe (21) with a peristaltic pump (2), with an inlet valve (22) at the inlet of the reactor (3). The entry of blood (S) into the reactor by the action of the peristaltic pump (2) is in slow mode.

- Once the incorporation of the amount of blood (S) in the reactor (3) is completed, the same amount of water (A) is added to the reactor. For this, the same system is used as for the blood, that is, from the initial deposit (1) and for means of the peristaltic pump (2) and the connecting pipe (21), water (A) is introduced into the reactor (3).

- Once the incorporation of the same amount of water (A) and blood (S) in the reactor (3) has been completed, the stirring blades (31) of the reactor are activated and the stirring of the mixture starts at low power and slow speed , to achieve a uniformity of the liquid without the formation of lumps.

- Without stopping the movement of the agitation blades (31), the diluted hydrochloric acid addition pump (4) adds said acid in the reactor (3) until reaching the point of acid pH to coagulate the whole mass, whose value is in the environment of 1.5 to 3 as strong acid.

- The agitation blades (31) continue to work and, then, the sodium hydroxide addition pump (5), slowly begins to incorporate this alkali in the reactor (3) until the pH level rises, up to a value in the environment from 4.5 to 5.5, approaching neutrality.

- Once the previous pH value is reached, the movement of the stirring blades (31) is stopped for a short period to check that the pH remains stable. The pH measurement is carried out by means of a pH meter (32) that reaches the bottom of the reactor.

- Checking the stability time of the mass, the application pump of hydrogen peroxide or hydrogen peroxide (6), adds this component in the reactor (3) to begin the discoloration work, the stirring blades (31) arrested.

- After a long period of time counted from the first addition of hydrogen peroxide, the same quantity of oxygenated water is added back to the reactor (3) with the same system and methodology (6). In this way the installation is maintained in the waiting phase.

- After a few hours have elapsed since the oxidation has begun, and in view of the data indicated in the reactor detectors (3), a series of calculations is carried out to carry out the precise modifications to achieve maximum effectiveness in the discoloration and for this purpose it should modify the pH with the addition of hydrochloric acid (4) and / or hydrogen peroxide (6), to create the optimal working conditions.

- Once the time passes and the pH is corrected and neutralized, the team adds these components and starts and stops the agitation blades (31) only to stabilize and neutralize the mixture as many times as necessary, so that the mixture neutralizes little by little until it reaches a pH value around 7.

- Next, the colloid mill (7) is put into operation. The actuation process of the colloid mill (7) is such that the discharge opening (33) of the reactor is opened and a mono pump (34) that extracts product from the reactor is started, enters it in the inlet (72) of the mill colloidal, the colloid mill acts on the mixture, and this one conducts it again by means of conduits (71) to the interior of the reactor (3) generating a closed circuit.

- After a few minutes of recirculating the mixture, the pH values in the reactor are calculated with the meter (32) and the necessary compound is added to correct the acidity that the product may have.

- When the content of the reactor (3) is a yellowish mass, with a micronized appearance, which is observed with a peephole (35), the bypass valve (73) is opened so that the product is led to the lung reservoir (8) operating the agitator (82). Similarly, when the reactor (3) remains empty, it is proceeded to drag the remains of product, which are recovered along with those of the pipes (71) and the colloid mill (7), and are driven and introduced by its mouth of entrance (81) in said lung deposit (8).

- After the emptying, the stirring blades (31) of the reactor, the mono pump (34), the colloid mill (7) are stopped and the discharge opening (33) of the reactor is closed, so that afterwards all of this is washed with network water to remove traces of solid matter that may have adhered to the walls. Again, the discharge mouth (33) of the reactor is opened and the colloid mill (7) and the mono pump (34) are put into operation. These first washing waters they drag all remains of PHD solids that exist in the reactor, mono pump, colloid mill and pipes to the lung deposit. Once this operation has been completed, it is now possible to thoroughly clean the equipment whose washing water is channeled to a sewage treatment plant. Once the cleaning has been completed, the previous stages can be restarted successively to load another new reactor with new raw material or stabilized blood from the abattoir slaughterhouse.

- Once the blood (S) has been subjected to the hydrolysis and discoloration phase, the resulting product is entirely in the lung reservoir (8), shaking until it stabilizes.

- When the product is stabilized, the lung tank (8) transmits a signal and the following equipment is started: the centrifugal filter pump (9), an auger for extracting and transporting cake in an auger (93) and a pump monkey (83) feeding the centrifuge through the mouth (91). The centrifugal filter pump (9) is charged at low speed so that the solid is retained while the water of reaction is expelled; it is followed with the introduction of network water to extract and wash the salt content; when the level of salts detected at the outlet of the washing water is low, the washing water is stopped and the machine is automatically accelerated until it stops expelling water; then the revolutions of the centrifugal filter pump descend to the discharge level and, then, a hydraulic blade descends in the interior that scrapes to detach the product or compact cake that falls into an internal hopper (92) which is located in the lower part of the tank. the centrifugal filter pump (9); and finally, the extraction auger (93) collects the drained cake and transfers it to a hopper (10) designed to feed the dryer (11) that continuously generates the final product.

- The dryer (11) receives the wet cake that is dehydrated in a regular and continuous manner, where once the product is dehydrated, ground and cooled it is packaged under conditions that guarantee its perfect conservation in suitable containers.

On the other hand, in Figure 2 you can see the representation of the water cycle with the different phases and equipment of the procedure, which is important from the environmental point of view. In particular it can be said that network water is used which is both mixed with the stabilized blood from the slaughterhouse itself and with the different reagents previously described in the different stages of the process. Initially, both water (A) and blood (S) are included in the reactor (3), producing a mixture (I) without foaming, adding hydrochloric acid (4), sodium hydroxide (5) and hydrogen peroxide ( 6), so that the hydrolysis (II) occurs, then the discoloration (III), the colloidal phase of recirculation (IV) is reached with the mill (7) and stabilization of the pH (V), for a later transfer (VI) to the lung tank (8), washing and filtering (VII) in the centrifugal filter pump (9). At this time dehydration (VIII), micronized (IX) and packaging (X) are produced in the hopper (10) and dryer (11), while on the other hand wastewater (XI) is produced after filtering and washing (VI), said waste water being passed through a column of activated carbon (XII) and an osmosis plant (XIII), producing brine (XIV) on the one hand, and water taken to an evaporator (XV) with which evaporated water is properly produced and also reusable water (XVI) is obtained again in the whole process.
