Definitions
- the oven presented here is intended for the treatment and profit of the residues of organic and inorganic matter.
- residues from the food industries - such as fish residues, bagasse of olives, animal blood, bones, rendered fat from ruminant animals, fat from animal carcasses in poor condition of conservation, when they cannot be part of the food distribution chain - and still for the treatment and the profit of inorganic matter or mixtures of this matter with organic matter, like, for example, vases which result from filtration of beer or sludge with slag which result from the fusion of metals.
- the already existing ovens for treating organic residues use methods in which the steam is used for the treatment of the same residues, to allow the extraction of unctuous substances, which has the energy disadvantage of spending a considerable amount amount of energy to evaporate the water, and also to remove the water from the residues, which comes from the condensation of this same vapor, with the humidity inherent in these residues.
- the water vapor which has not been condensed must be treated later so that it can remove its odors and separate the vapors from the fats which form during the treatment time.
- the oven in question which operates without using steam injection because it works dry, is essentially composed of an enveloping carcass, inside which a drum slowly rotates which encloses the product we want treating and wrapping an axis provided with several blades and a scraper which has the function of avoiding sticking of the material in transformation to the interior surface of the drum during its treatment. Despite this same axis coinciding with the axis of the drum it is not united with it, but it turns anyway.
- the attached drawing is presented as an example and not with a limiting objective, it shows the best way to carry out the present invention, where the drum (A) and the axis (B) are actuated respectively by the geared motors (C) and (D) and by pairs of gears (E), where the axis is supported on bearings (F), which are inside the two sleeves (G) of the covers (H) of the aforementioned drum.
- the cylindrical drum (A) already mentioned has circular lines in the covers (H) which exist in its ends - which are attached to the drum already attached by a few points which cause small interruptions in the lines already mentioned - these same lines are vertically aligned with the inlets of the two tubes (M) for collecting the liquid part (aqueous and unctu ⁇ ous) of the material to be transformed.
- the oven during its operation, has two distinct phases.
- the drum (A) after being loaded with the product to be processed, turns slowly, so that it slightly agitates the product already added, at the same time as it is heated, to allow the release of its liquid part (either aqueous or unctuous) that, by gravity, falls into a casing (M) to collect liquids through the middle of the lines that exist in the drum.
- the inner axis (B) does not move, the scraper (L) is in the highest position, and it only serves to help promote the movement of the material that strikes against these blades (J), which are also stopped, and also to scrape the inside of the drum (A) so that the product which flows inside can be removed as it dries.
- the second phase begins when the liquid stops falling through the lines.
- the drum (A) maintains its rotational movement to allow not only a uniformly warm product inside, but also that the product is completely stirred, without causing an accumulation in this same area of the drum and consequently to prevent the product from slipping through the lines of the same drum.
- this slow rotational movement also makes it possible to clean the lines in the vicinity of which the product has accumulated, namely in the edge of the side covers (H) of the drum, once in the upper side of the drum (A ) already attached there are two flakes (I), one in each line, which clean the existing product there, as this product, by accompanying the movement of the drum (A), strikes the flakes already reported , which take off and move the product from the walls of the covers (H) of the drum, after it falls again into the interior of the drum.
- the glitter action (I) is further enhanced because the product attached to the same flakes is peeled off each time one of the points of union of the drum with the respective cover hits the flake, which bends when it passes, after it, due to its elastic composition, Abruptly returns to its original position and it is released from the material that can be attached, which falls into the interior of the drum.
- the second phase is not necessary - once as they are hard they do not tend to attach to the walls of the drum and its weight and sufficient for them to be agitated suitably and can be released from water and fat - which they do not end up in powder like other products, ie those which are initially presented in a pasty or coagulated state.
- Another way of carrying out the present invention consists in an oven in which the drum (A) is open in the upper side, this same drum has a cross section with the shape of a "U” which does not allow it to rotate , on the other hand it performs an alternating rotary movement, with an angular amplitude small enough so that its content is not discharged.
- the loading of the drum is carried out directly, without it being removed from the oven, and the unloading is done by the bottom of the oven - for example by the middle of a rolling carpet - by turning the drum of 180 ⁇ . which causes the discharge of its contents, by which warmly is lateral and not by the bottom as in the embodiment previously described.
