Definitions
- the present invention is a granulate that can be used as a "cat sanitary granulate” because of its high power to absorb liquids and / or moisture from solid waste. Also described is the production process of said granulate, obtained through the processing of vegetable fibers, cassava mass (residue from industrial processing) associated with sugarcane bagasse with water.
- mineral granules (clay, bentonite, sepeolite, silica), wood and processed cereals.
- these materials have some disadvantages, such as: clay pellets generate a lot of dust, have low odor neutralization efficiency and have high density (they are very heavy); Processed cereal pellets have low durability and form easily crumbling clods, and their raw material can be used for human consumption; and silica pellets do not clump together, resulting in great waste due to the need to change the entire contents of the litter box at short intervals (7-10 days).
- an ideal composition consisting of mixing cassava pasta (a by-product of the food industry), sugarcane bagasse, minerals and water.
- the granulate obtained is able to meet the demand of consumers regarding hygiene, practicality, odor neutralization, lightness, clod firmness and sustainability.
- the first objective is achieved by a granulate for the absorption of liquids and moisture from solid waste, comprising fibrous bran, vegetable fibers (sugarcane bagasse), water and minerals.
- the second objective is achieved by the process of preparing granulate for liquid and moisture absorption of solid waste comprising the following steps: a) obtain the source of fibrous bran;
- step (e) grinding the granules obtained in step (e);
- the third objective is achieved by the use of a granulate as a hygienic granulate for domestic animals.
- Figure 1 Illustration of the granulate of the present invention agglomerated after urine dose simulation.
- the granulate comprises, in percentage by weight in relation to the total weight of the granulate:
- the fibrous bran is starch obtained through the mass of cassava, more precisely the dried solid residue from cassava processing.
- Cassava processing is carried out by the food industries that do so after peeling, washing and thus obtaining the raw material used, for example, for tapioca flour and gum production. (products for human consumption). As a result of this processing, a low starch liquid undesirable for the food industry is obtained. This low starch by-product undergoes a drying process resulting in the residue used as the raw material for the hygienic granulate described herein.
- said dried solid waste from cassava processing contains 6% to 10% fiber.
- the minerals found in this granulate are derived from cassava processing. The percentages of these may vary according to the characteristics of the soil, the fertilizers used and the climate where cassava was planted. However, these indices are generally not found above a total of 10% by weight relative to the total weight of the granulate.
- the minerals present in the granulate composition are selected from, but not limited to, Calcium, Magnesium, Potassium, Iron, Phosphorus and mixture thereof.
- ashes and fats may be added in the formulation as additional components.
- ashes and fats are added at the concentrations of:
- the granulate grains are between 0.20 and 4.00 mm in size.
- the density of the granulate results in the best weight ratio of product by volume absorbed, where no dust is formed and the agglomerate is as shallow as possible.
- the density of the granulate is from 200 to 350 g / l (0.20 to 0.35 g / ml).
- the granulate described herein has some native characteristics as a result of its composition, namely:
- the product described herein can be used as a "hygienic granulate" for pet use.
- said granulate is not harmful to animal health, or to those who manipulate it, since it contains no toxic ingredients. It is still practical and hygienic as it does not generate dust.
- the granulate has the characteristic of forming firm and easy-to-handle clumping, has a particle size that is free from dust and has an excellent yield. Just 1.3kg is enough for about 30 days for a 4kg adult cat, unlike cereal-based products that have 3kg packages for the same durability, and clay products that need an average of 4kg for 30 days. .
- the process for obtaining the granulate comprises the following steps:
- step (e) grinding the granules obtained in step (e);
- the fibrous bran is starch obtained through the mass of cassava, more precisely the dried solid residue from cassava processing.
- Cassava processing is carried out by the food industries which do so after peeling, and thus obtain the raw material used, for example, for tapioca flour and gum production (human food products). ). As a result of this processing, a low starch liquid undesirable for the food industry is obtained. This low starch by-product undergoes a drying process resulting in the residue used as the raw material for the hygienic granulate described herein.
- said dried solid waste from cassava processing contains 6% to 10% fiber.
- the grains of the granulate are between 0.20 and 4.00 mm in size.
- the density of the granulate results in the best weight ratio of product by volume absorbed, where no dust is formed and the agglomerate is as shallow as possible.
- the density of the granulate is from 200 to 350 g / l (0.20 to 0.35 g / ml).
- the extrusion process begins at a temperature from 130 ° C.
- the operating time of the extrusion process is up to 2 minutes.
- the product obtained is not subjected to drying by heat source (eg boiler), but is taken directly to a controlled cooling step at room temperature, where partial drying is achieved by drying. flashing, due to the sudden change in temperature (from 160 to 200 ° C for room temperature). Residual moisture is controlled to a maximum of 17%, and is an important part of activating the clumping effect of the product.
- heat source eg boiler
- milling occurs due to the need to expose the porous cavities within the extruded granules for better absorption of the liquid.
- the "aeration" effect of the product obtained by the extrusion in this case is what produces the cavities where the liquid waste accommodates.
- this liquid is released and the moisture is exceeded from its control value, it activates the extruded gelatinized starch, causing the desired agglomeration.
- natural fragrances may be added to the granulate to impart a pleasant odor to it.
- Such fragrances may be selected from, but not limited to, lemongrass and / or coconut flavoring, or any other suitable for application to said granulate.
- Granules of the present invention cassava dough based product with sugarcane bagasse
- the granulate of the present invention used in the tests has the following composition:
- the granulate of the present invention was conditioned for 24 hours at 50 ⁇ 2% relative humidity and 73 ⁇ ° C.
- the pellet was soaked in 0.9% sodium chloride solution at room temperature for 15 minutes, and then drained for one minute over a 0.60 sieve. mm
- the granulate mass was then weighed.
- the amount of solution absorbed was calculated together with the absorption per gram.
- the average in grams of the absorbed sodium chloride per gram of the granulate of the present invention was 8.04 grams. The results obtained are shown in Table 1 below.
- a 30 milliliter solution of 0.9% sodium chloride in water was used to simulate a single dosage of cat urine. This solution was poured into a granule container of the present invention which had a 70 mm deep granule layer. After 10 minutes, the formed agglomerate could be removed from the container without fragmenting. This was repeated in the 5 samples tested.
- a 30 milliliter solution of 0.9% sodium chloride in water was used to simulate a single dosage of cat urine. This solution was poured into a container containing the granulate of the present invention with a total thickness of 70 mm deep. After 1 hour, the cluster formed was measured at approximately 50 mm by 50 mm ( Figure 1). The cluster can be removed and handled without breaking it.
- the percentage of dust was calculated by placing a cat litter bag in a vacuum-sealed system. The amount of dust particles collected on a vacuum filter was weighed and compared to the initial weight of cat litter. The granulate of the present invention was calculated to be 99.99% dust free. The results obtained are shown in Table 10 below. Table 10 - Percentage of Dust Accumulation - Granulate of the present invention
