Description

Get rid of device of mould in hydrocolloid powder
Technical Field
The invention relates to a device for removing mould in hydrophilic colloid powder, belonging to the technical field of production equipment of high-molecular polysaccharide hydrophilic colloid.
Background
The mold is one of fungi, is commonly called filamentous fungi, and means 'mildewed fungi'. Can form branched mycelium, and can grow villous, flocculent or cobweb-shaped colonies which are visible to the naked eye in a certain moist and warm environment, and the fungi are obtained. When growing on a solid substrate, part of the hyphae penetrate into the substrate to absorb nutrients, and are called substrate hyphae or nutrient hyphae; aerial extension is called aerial hypha, which can further develop into breeding hypha to produce spores called mold spores. A large number of mycelia are interlaced into a villous, flocculent or net-like shape, and called as mycelia. The mycelium often appears white, brown, gray, or bright in color, and some may produce pigments to color the substrate. The mold is fast to breed and often causes a great amount of mildew and rot on foods and utensils, but many beneficial species are widely applied and are the first microorganisms utilized and recognized in practical activities of human beings.
The mold can be spread and propagated through tiny spores. Can be suspended in air for a long time and continuously diffused by environmental factors, and the stability of the spore can ensure that the spore is suspended in the air for hours or days. After human inhalation, the harm is small when the number of mould spores is very small, but as the number is increased, the health threat to human body is more and more serious health problems are brought, especially for people with poor physique immunity, and the known allergic reactions comprise: asthma, urticaria, pulmonary infection, rhinitis, headache, fever, diarrhea, etc.
The harm of the mould is not only harmful to human health, but also has wide influence on production and manufacture, and causes huge economic loss to health care, food, planting industry and catering industry. In addition to causing visible spoilage, molds produce mycotoxins, and more than 200 molds have been identified in food products to produce substances harmful to human health, mainly including aflatoxins, moniliformin, herceptin, patulin, trichothecenes, and zearalenone.
The treatment of the mould and the control of the mould pollution source are always difficult and painful points in various industries, and improper treatment not only causes direct economic loss, but also seriously threatens human health. The reason why mold easily occurs in general factory plants: 1. the walls or corners of the production workshop are wet, and in addition, a part of products are not cleaned in time, so that mold is easy to grow on the wet parts. 2. The workshop air purification system does not normally operate, so that outdoor mould enters a workshop through ventilation, and the mould is easy to grow under the condition that the humidity is not timely guaranteed in the workshop. 3. The equipment is not sterilized or cleaned before production, and is gathered for a long time, so that mould is easy to grow on local positions and is spread through spores, and the production environment is polluted. 4. Mold can also grow due to the moist storage environment and aggregate on the ground. 5. The air inlet of the equipment is not provided with a filter or a filter screen or is not cleaned for a long time, and the mould is brought into the workshop or the equipment during ventilation. 6. The valves and pipelines are not cleaned in time after production, and the valves and pipelines are not disinfected before production, so that the mould is bred due to the aggregate in the valves and pipelines. 7. The sterilization process is immature, the mould cannot be sterilized thoroughly, and the like. 8. Staff do not do disinfection protection as required, enter the workshop and do not clean clothes, and bring the mould into the workshop.
The fungal spore coat, which comprises 80% of the total spore protein, is responsible for spore resistance to chemical disinfectants, while bacterial endospores and fungal spore germination are accompanied by increased metabolism and perception of heat, and the environment must be perceived to be sufficient to support their growth and reproduction before germination. The most common sterilization methods at present include ultraviolet methods, chemical sterilization methods, high temperature methods, physical methods and the like, but the spore killing of various industries is difficult, and the common sterilization methods include a method for sterilizing spores by high-temperature and high-pressure heating, and the method can bring irreversible damage and degradation to some products such as the viscosity, the color and the molecular weight of high-molecular polysaccharide hydrophilic colloids.
The prior art methods for controlling mold in production plants are largely divided into environmental control and direct killing. The sterilization method includes ultraviolet ray method, chemical sterilization method, high temperature method, physical method, etc.
For example, patent document CN107105641A discloses a disinfectant, which is obtained by bringing an aqueous solution containing hydrogen peroxide, organic phosphonic acid, etc. into contact with an object in the form of mist or vapor by heating. For example, patent document CN213848591U discloses a sterilization apparatus for food processing. The device improves the stirring uniformity of the materials in the sterilization process, solves the problem that the objects shake in the moving process, improves the sterilization efficiency of the objects, and realizes the control of the survival amount of harmful bacteria in food. For example, patent document CN213307266U discloses an indirect sterilization device for powdered food, which comprises an air draft system and a sterilization tank, and solves the problem of small gaps and poor air permeability of the powdered food, thereby improving the ventilation effect and reducing the breeding of harmful bacteria.
The methods have the problems of chemical residue, large equipment investment, complex process, poor continuity, high energy consumption and the like in different degrees, and have the defects of not killing and removing powdery mildew produced in large scale, having poor removing effect or damaging colloid quality and the like.
