The processing of pet food extrusion machinery is mainly through a variety of different means , and various raw materials are added to pet food extrusion machinery to make shaped food. This kind of food can meet the nutrients required by pets. The pet food extruder is not only used as the staple food of pets, but also has a good improvement in the palatability and digestibility of pets.How To Use Extrusion Machinery For Pet Food?

pet food machine

Dog food is one of the categories of pet food. The dog food extruder machinery’s range of dog food is very wide, including pet snack food, dental sticks, bones, nutrient liquid, nutrient powder, and dry food, wet food, semi-dry food, canned food, etc. In order to make pet food plays a large degree of nutritional function, different raw materials are processed in different forms and degrees.

The processing of puffed dog food is basically divided into three categories: physical method, chemical method, and microbiological method. The physical method mainly refers to the extrusion, heating, crushing, and bonding of raw materials, and the chemical method is to denature starch and degrade protein. The microbiological law refers to the fermentation of a certain raw material.

In the past technical guidance work, we have been to some pet dog farms, and they are also making some dog food. However, in order to reduce the input cost, some individual dog farms choose some small pet food extrusion equipment without extrusion process and there is no post-spraying process. After pet dogs eat the dog food produced by pet food extrusion equipment, they often suffer from diarrhea and anorexia.  This shows that extrusion puffing, spraying these two core processes in the production of pet food is important.  

pet food production lineLoyal Industrial is located in the beautiful spring city of Jinan. The company has long been engaged in the research and development of pet food extrusion equipment and production technology. The company has standardized production technology, automatic control operation concept, and is focus on the development of stable and reliable extrusion production equipment. The company has responsible on-site engineering personnel engaged in production and commissioning work, standardized design production commissioning process, can provide you with services.

China leading the way to second hand clothes

First, The data shows that, on average, each person in China buys about 10 new clothes each year, of which 3-5 pieces of clothes are discarded.

Approximately 50 million tons of clothes are discarded every year, which most of the dropping off second hand clothes are barely worn.

And plus the BBC reported that China' new policy of opening three-child in 2021, the trend of be discarded 2nd hand fashion clothes will be increasing.

Second, Though the global export market for worn and used clothing is estimated to be about$4bn,

Among them US which is the world’s biggest exporter of worn clothing,but due to the COVID-19 situation, there is lack of labour.

Mrs A, who has been in the clothes recycling business for 30 years, she says it’s hard to remain competitive when labour costs in the US are quite high.

In contrast, In China, there have enough labour without be effected by the situation,

the cost of pre owned fashion used clothes raw material be low and be more competitive.


where is the China's used clothes going?

There are 10% to 20% of used clothes are sold through charity shops.

The rest are selling clothes online to distributors or retailer.

such like Guangzhou Hissen Global factory, which is suppliers to sort the used clothes for different grade to 

and send them to the place like Africa or Middle east where they are sold in second hand outfits markets.

What Is a Scale Inhibitor?

Scale inhibitor is a class of agents that can disperse insoluble inorganic salts in water, prevent or interfere with the precipitation of insoluble inorganic salts on the metal surface, scale function, and maintain good heat transfer effect of metal equipment.
Scale inhibitors can remove scale and prevent scale formation, improve the efficiency of heat exchange, reduce electricity, or reduce fuel consumption; water treatment can also reduce sewage, improve the utilization rate of water, and generally save 60% or more.


Classification of scale inhibitors

According to the polymeric composition of the scale inhibitor, it can be divided into two categories: natural polymeric scale inhibitors and synthetic polymeric scale inhibitors. Synthetic polymeric scale inhibitors can be further divided into carboxylic acid polymeric scale inhibitors, sulfonic acid polymeric scale inhibitors, phosphorus-containing polymeric scale inhibitors, and environmentally friendly scale inhibitors of 4 kinds.

1. Polycarboxylic acid scale inhibitor and dispersant

Polycarboxylic acid compounds have a good scale inhibitory effect on calcium carbonate scale, and the amount is very small. Commonly used are polyacrylic acid PAA, hydrolyzed maleic anhydride HPMA, AA/AMPS, multi-component copolymers, etc.

2. Organic phosphonate

Organic phosphonates are more effective in inhibiting calcium sulfate scale, but are less effective in inhibiting calcium carbonate scale. It has low toxicity and is easily hydrolyzed.

3. Organic phosphonic acid scale inhibitor

Commonly used are ATMP, HEDP, EDTMPS, DTPMPA, PBTCA, BHMT, etc., which have a good effect on inhibiting the precipitation or precipitation of calcium carbonate, hydrated iron oxide or calcium sulfate.

4. Polyphosphate

Commonly used polyphosphoric acids are sodium tripolyphosphate and sodium hexametaphosphate. Long-chain anions formed in water are easily adsorbed on tiny calcium carbonate crystals. At the same time, this anion is easy to replace with CO32-, thereby preventing the precipitation of calcium carbonate.


The mechanism of action of scale inhibitor

In terms of mechanism of action, the action of scale inhibitors is divided into four parts: chelation solubilization, coalescence and dispersion, electrostatic repulsion, and crystal distortion. And in the laboratory evaluation test, dispersion is the remedy of chelation. Lattice distortion is the remedy of dispersion.

1. Chelation Solubilization

The process of bonding two or more coordination atoms of the same polydentate ligand with a central ion and certain conditions to form a complex with a ring structure is called chelation. The result of chelation is that the scaling cations (e.g., ca2+, Mg2+, etc.) interact with the chelating agent to form stable chelates, thus preventing them from coming into contact with the scaling anions (e.g., CO3 2-, SO42-, PO43-, and SiO32-, etc.), which greatly reduces the chance of scaling.

2. Coalescence and Dispersion

The result of dispersion is to prevent the mutual contact and coalescence of scale-forming particles, thus preventing scale growth. Scale forming particles can be calcium or magnesium ions, scale forming particles consisting of thousands of CaCO3 and MgCO3 molecules, dust, silt, or other water-insoluble matter. Dispersants are polymers with a certain relative molecular mass (or degree of polymerization). The level of dispersion performance is closely related to the size of the relative molecular mass (or degree of polymerization).

3. Electrostatic Repulsion

The effect of electrostatic repulsion is that the copolymer dissolves in water and adsorbs onto the inorganic salt crystals, which increases the repulsion between the particles, hinders their coalescence, and puts them in a well-dispersed state, thus preventing or reducing the formation of scales.

4. Crystal Distortion

The effect of lattice distortion is that some of the functional groups in the molecule occupy a certain position on the inorganic salt nucleus or grain, hindering and disrupting the normal growth of the inorganic salt crystal, slowing down the growth of the crystal reducing the formation of salt scale.

As can be seen, scale inhibitors are effective in dispersing insoluble inorganic salts. The chemicals in them effectively prevent the coalescence of dirt, thus achieving scale inhibition, which also has a great industrial effect.


Performance of scale inhibitor

The scale inhibition effect of scale inhibitor is due to its ability to stop the growth of small carbonate crystals and deform the lattice so that the carbonates do not exchange heat in the circulating cooling water. Hard scale is formed on the surface of the equipment. In contrast, the organic phosphate and other components in the tissue form a protective film with the metal. It combines with the calcium ions in the circulating cooling water to prevent metal corrosion. The PH value of this product is applicable in a wide range, between PH value 7.0-10.0 have scale inhibition and corrosion inhibition, so that industrial production and operation is simple and will not cause corrosion and scaling due to uncontrolled PH value. The ultimate carbonate hardness of the product can reach about 680mg/L, with a good scale inhibition effect.

Understanding the performance of the scale inhibitor can be widely used in various industries to give full play to its performance. At the same time, with the continuous development of technology, the performance of scale inhibitors is also improving to expand the scope of use of the product and promote the development of scale inhibitors.
