Definitions

  • the invention provides a solution for calibrating in two categories, in a fluid, materials with varying volumes and densities close to the fluid used after total immersion in this fluid.
  • Centrifugal separation of materials immersed in a fluid is common. These materials must be of substantially different density from that of the fluid, on the one hand. On the other hand, in the case of a random mixture of materials with different volumes and shapes, their separation into two groups becomes difficult by simple centrifugation: a self-sieving effect is created by amalgamation of the materials of the two groups between they, because of their more or less bulky or hanging forms.
  • Too much fat makes it difficult to dry, and this dries more fat in the pen. Excessive fouling of the pen alters its actual weight, and thus disturbs the calibration by the suction method in columns. Finally, a fouled feather can also be smelly, and in turn foul the machines used for the treatments before washing.
  • the invention is at this level of its interest: knowing that on a bird, such as duck for example, 35 to 45% of the weight of the feathers are put in non-recoverable waste for bedding at the end of the complete process of feather treatment (washing, parboiling, dusting, storage, transport, etc.), it is best to separate before any treatment of feathers those that are intended for the bedding of those that will be sent to the squarers.
  • the prototype according to the present invention, used on feathers gives a striking result.
  • the invention allows several calibration results by sieve modification. It is possible, in the example of the feathers, to separate the feathers of sizes greater than about 5 centimeters, others of different sizes and shapes but smaller.
  • the invention provides a method, and a preferred machine, for calibrating with a fluid materials between them, more or less voluminous, and whose densities after total immersion are close to the fluid, or lower.
  • the principle of the invention is to maintain suspended in the fluid, materials to be calibrated during the calibration process. Indeed, the holding in suspension allows to separate one by one the elements that constitute the initial material to be calibrated.
  • a permanent fluid stream passes through a sieve, this fluid drives with it the finer elements in proportion to the sieve openings.
  • the staggered stirring of the fluid mixture and materials to be calibrated prevents these materials from being amalgamated with one another by caking or amalgamating at the inlet of the sieve orifices during the displacement of the upstream fluid downstream. sieves.
  • This mixing can be achieved by a tree and blades, creating a slight centrifugal effect in a vertical cylinder or not.
  • This centrifugation effect is interesting in the case where the materials to be calibrated are of different relative densities and of which those intended to pass through the sieves are denser than the others, thus facilitating sieving by bringing these materials closer to the sieves located on the periphery of the sieve. the walls of the brewing chamber.
  • This mixing may be the occasion of a chemical treatment in an aqueous medium of the materials to be calibrated, by addition of surfactants or other, and this during the calibration process, in a closed circuit as to the fluid used.
  • surfactants can improve the wettability of materials, color, disinfect, or other effects.
  • a surfactant, or additive can also be used to modify in aqueous medium the relative densities of the fluid and the materials to be calibrated, in order to improve the propensity of the substances to remain in suspension in the fluid after immersion in this fluid. .
  • This larger enclosure has a discharge orifice (7) equivalent flow rate to that entering (9) in the small enclosure, the fluid level remains stable and substantially equal between these two communicating speakers.
  • the materials to be calibrated go, or do not go, one by one, follow the path of the fluid through the screens according to the characteristics of the latter. At this stage, the calibration is all the more perfect as the circulation of the fluid is slow at the sieves.
  • a second method of application of the invention is to divide the same enclosure ( figure 5 ), using sieves, in two superimposed zones (1 and 2), with fluid flow, by gravity, from an upper zone (1) to the other lower zone (2), via sieves (3) ).
  • Fluid evacuation (7) from the downstream zone of the screen creates the flow, but this flow is regulated according to the size of the sieves and the materials to be calibrated in order to avoid bottlenecks at the sieve entries.
  • a compromise is to be found to obtain a speed of calibration, or productivity. This compromise depends, among other things, on the number of orifices constituting the sieve and on the fineness of the desired sizing.
  • the characteristics of the sieve will depend on the materials to be calibrated.
  • the sieve consists of two main parts. One is composed of multiple tubes (15), juxtaposed in linear series. These linear series of tubes are positioned on the walls of the stirring chamber (1) perpendicular to the direction of the stirring made in this chamber ( figure 4 ). The other is an output stop (23) for each series of tubes.
  • the tubes (15) juxtaposed in rows, or checkerboard form the orifices (22 and 23) of the sieves and have a shape and a size adapted to the materials to be calibrated during their eventual passage through the sieves.
  • These tubes (15) are of identical shape, more or less elongated (A) and diameter (C) more or less important.
  • Each tube will preferably be unstretched to eliminate any risk of blockage of materials having curved shapes and bad luck positioned in the opposite direction of the curved shape of the tube.
  • the sieve abutment (17) forms a bend (18) approaching 90 degrees, open on one side (20) to allow flow of fluid and material passing through the sieve.
  • This stop will have its opening (20) rotated in the direction of mixing the fluid in the sieving chamber.
  • This stop will be positioned at the outlet (23) of the sieve tubes, but at a distance (B) sufficient to allow the flow of the fluid and materials thus selected.
  • the cumulative length of the tubes and the space between the ends of the tubes and the abutment (A + B) is such that the elements that are too long can not pass beyond this sieve.
  • a material such as a feather (19) for example, engaged in a tube (15), coming into contact with the stop (17), and of a length such that it does not sufficiently exceed the inlet orifice (22) of the tube, then a compromise between the sizes A, B, C and D of the sieve must allow this material to continue its way downstream of the sieve, aided by friction, in the sieve parts, the fluid alone or the fluid loaded with materials.
  • the goal is to not obstruct the screen openings so as not to create a bottleneck effect for the flow of fluid and any materials.
  • a closed circuit for the fluid saves the amount of fluid to be used during the calibration process.
  • the selected elements after passing through the sieve, then the passage in the chamber (2) serving as envelope to the first ( figure 1 ), and finally the passage beyond the valve (7) for emptying the same second chamber, are separated from the fluid by a separator device. Beyond this separator, the purified fluid of the selected materials goes back by a device, pumping for example, upstream of the calibration process located at the enclosure with sieves. As for the selected materials, they are grouped together and sent to a storage or treatment area other outside the invention.
  • the principle is based on the flow of a fluid from an initial zone, to a secondary zone, via a sieve, with the help of a continuous supply of fluid upstream of the system, proportional to the flow of fluid leaving the zone.
  • secondary by a drain valve effect of communicating vessels. This fluid will cause some of the elements contained in the initial zone towards the emptying of the secondary zone.
  • the prototype developed proposes a preferred embodiment of the invention applied to the raw duck feather, wet.
  • a vertical cylindrical tank (1) such as a standard 200-liter drum, positioned in a tank (2) of any shape but of sufficient height to allow the immersion of about three-quarters of the cylinder height ( 1).
  • This cylinder (1) is provided with sieves (3,4 and 5) distributed on its periphery, in vertical rows of orifices in sufficient number to allow a fluid flow sufficient for the productivity of the calibration. These columns of orifices are as high as the cylinder itself, with the exception of a shift at the base of the cylinder in the case of heavy particles such as metal parts, pebbles, volatile offal in the case of calibration of feathers coming from directly from slaughterhouse, or others, which can be deposited at the base of the cylinder. Thus, these heavy and undesirable particles, sometimes small volumes, do not cross the sieve, do not deteriorate and do not obstruct it.
  • This cylinder is traversed by a motorized rotary axis and provided with blades (6). These blades graze the sieves.
  • the sieves are a series of small tubes (15) square or not, about 2 to 5 centimeters (C) side or diameter, and about 3 to 5 centimeters (A).
  • a plate (17) serving as a stop is fixed on the side of the outlet (23) of the tubes so that the elements that are too long or too rigid, which will engage in the small tubes, abut on this plate, and turn back in the cylindrical tank thanks to the action of the stirring in this cylinder.
  • the materials or the bubbling fluid will release these elements momentarily stationed in the small tubes of the sieve, releasing the orifices (22) again to continue the calibration.
  • This abutment plate (17), bent (18) is spaced from the outer end (23) of the tubes approximately 2 to 3 centimeters (16), and open (20) from the side opposite to the direction of the stirring of the fluid in the cylinder.
  • an element (feather for example, Figure 4 ) of length much greater than A + B, coming into abutment on the abutment plate (17), tends to be positioned at an angle in the direction of stirring (19). It is therefore appropriate that the base of this feather element remains in abutment until its release by stirring, without the risk of being driven by the constant stream of fluid converging towards the outside of the cylinder through the screen.
  • An enclosure serving as envelope (2) receives the charged fluid of the selected materials (8) at the exit of the screens.
  • This enclosure of any shape but tight surrounds the cylinder (I) because in our embodiment of the invention, the screens are distributed over its entire periphery.
  • This enclosure, enveloping the cylinder, has a level of fluid necessarily close to that of the cylinder.
  • the circulation of the fluid is ensured by a supply (9) of the cylinder (1), and a discharge valve (7) variable flow at the outlet of the enclosure envelope (2).
  • the flow rate of the fluid will be almost identical at all stages of the calibration process, including the following three places: feeding from the top of the initial cylinder, passing through the orifices of the sieve, and finally the emptying of the enclosure-casing.
  • a non-foaming degreaser for example, will prewash the pen during the calibration process.
  • a surfactant added to the fluid for example water, can also improve the wettability of the pen.
  • the amount of raw feathers to be introduced into the cylinder (1), equivalent in dry weight, is about 3 to 7 kilograms for the cylinder of the prototype having 50 centimeters in diameter and 80 centimeters in height. The more the initial material consists mainly of elements not crossing the sieve, the lower the amount of material to be introduced at the beginning of the calibration cycle. Indeed, the calibration will be less effective if during the entire duration of the calibration the stirring cylinder is saturated with elements intended to remain prisoners of the cylinder. The stirring of course improves the calibration by unclogging the sieve at regular intervals.
  • the calibration process can then start by simultaneously opening, at equivalent flow rates, the supply valve (9) with fluid from the top of the cylinder, and the drain valve (7) located at the outlet of the tank-casing.
  • Calibration time for 4 kilograms, is 3 minutes with the prototype. This productivity can be multiplied by a sizing of the sieves, the size of the tanks and cylinders, the flow of fluid, etc.
  • the invention provides for recovering in a closed circuit (14) this fluid beyond the drain valve (7) after having purified the fluid of its feathers suspended by a separating device (10).
  • the feathers selected, because they have crossed the sieve, are removed from the system by means such as conveyor for example.
  • the water inlet above the cylinder must be sufficient for two reasons: On the one hand, moving the large feathers to the pipe (12), the effect of caking being reduced because of the stirring retained in the cylinder, and secondly, to avoid a reversal of the direction of flow from the tank (2) to the cylinder (1) by the effect of communicating vessels, this in the case where the level fluid flow in the cylinder would descend due to evacuation flow greater than that of the upstream supply, and thus back through the sieve feathers previously selected but remained suspended in the tank-envelope (2). This inversion of the flow direction of the fluid will partially lose the benefit of the calibration system, object of the invention.
  • the time to drain the feathers trapped in the cylinder can last a few seconds with an efficient flow of fluid and materials.
  • the valve (11) of the cylinder closes, and that (7) of the tank-envelope, opens again, to find the initial circuit of the flow for calibration from the mixing cylinder to the tank -wrap, through the sieves.
  • the loading of materials to be calibrated is then again possible, and the process follows the previously described steps.
  • the cycle thus presented of the calibration process can be modified according to the composition of the materials to be calibrated.
  • a material composed mainly of elements passing through the sieve avoids the discharge of trapped material upstream of the sieves at the end of each sizing process, the latter remaining in small quantities upstream sieves.
  • the calibration process then becomes as follows: Regular and continuous feeding of material upstream of the sieves into the stirring cylinder, then stopping the feed, and allowing the calibration process to continue as described by the invention over a period deemed sufficient, and then proceed to the actual emptying of the trapped materials upstream of the sieve in accordance with the process described by the invention. This process significantly increases the productivity of the calibration in the case of materials mainly composed of elements crossing the sieve.
  • the productivity per hour can reach several hundred kilograms of raw feathers entered in the machine, in dry equivalent weight, depending on the dimensions of the machine.
  • the invention allows a total and easy adaptation of the size of the system, by juxtaposable modules.
  • a tank-envelope can contain several cylinders equipped with stirring and sieves.
  • a brewing cylinder can also have a large size.
  • the invention eliminates most of the non-usable feathers for bedding, up to 40% of the weight of feathers entered the machine.
  • the machine allows to calibrate the feathers according to the desired lengths.
  • the treatment of feathers for the bedding is then limited only to the materials calibrated by the invention.
  • wet feathers from slaughterhouses are most often loaded with waste of all kinds, such as legs or heads of slaughtered animals, offal or even whole animals fallen from the slaughter line.
  • These intrusive materials make it difficult to wash the feathers in a single operation because of the odors caused during the steaming after washing.
  • the invention provides a happy answer by allowing prisoners to retain intruder elements within the sieving chamber because of sieves and the lower part of this chamber which serves as retention for these heavy materials.
  • the tests with the prototype made it possible to separate the feathers of sizes smaller than 4 cm, from those larger than this size, for a type of sieve having, on the one hand, smaller orifice tubes, and on the other hand on the other hand, a smaller distance between the end of these tubes and the stop, all things being equal.
  • This allows the use of the invention in successive steps in successive calibration sieves adapted, in order to calibrate in 3 or 4 different sizes raw materials in the same flow.
  • the first enclosure keeps the larger elements in captivity, the others flow to a second enclosure, which in turn keeps the intermediate-sized elements captive, etc.
