What are the factors that affect the quality of puffed food

What are the factors that affect the quality of puffed food

The influence of raw material composition on the puffing rate: for example, for grains, the influencing factor is the total amylose content. In the processing of puffed rice, the effect of moisture content on the puffing rate is very important. The puffing rate of the dehulled rice initially increases with the increase of water content; after reaching a certain level, it decreases with the increase of water content.

  1. Processing technology: gelatinization temperature of starch, addition of edible oil to grains, etc.
  2. Extrusion equipment: ① Screw: During the pressurization process, the pressure, shear force and heating temperature of the equipment all have an impact, but a relatively important factor is the length and diameter of the screw, and secondly, the rotation speed of the screw also plays a key role. The higher the rotation speed, the higher the temperature, the lower the residence time, the lower the torque, the higher the puffing degree, and the lighter the color of the product. ② Feeding: For the same mold, under the condition that other conditions remain unchanged, if the feeding is increased, the pressure will increase, the expansion degree will become lower, and the color will become darker.

In the process of puffed food processing, the direct cause of unqualified puffed food is generally the problem of seasoning. Due to the particularity of the puffed food processing technology, it has to undergo high temperature or even high pressure, and the semi-finished products have no problem in terms of microbial indicators. Quality of products. Secondly, in the processing of puffed small food, due to the addition of inappropriate food additives, such as aluminum-containing leavening agents, the aluminum content of the product will be too high. Some come into contact with alloys containing lead and tin, which will vaporize at high temperatures and may contaminate puffed food. There is also a source of aluminum that has not attracted widespread attention, that is, synthetic food colorings, colorants prepared by precipitation of their aluminum lake water-soluble pigments on alumina. In addition, there are still some problems such as extremely poor hygiene conditions in some processing points, and sour deterioration of some foods under bad conditions.

Shanghai HG Food Machinery Co.,ltd., whose head factory was built in 1970s. During its nearly 40 years’ experience an designing and manufacturing in food machine, it now has developed into an enterprise with strong technical power, great reputation in local and global market. HG enterprise now owns 4 machine processing factories, 1 food laboratory factory, 1 trading company, and 1 poly-tech university with an annual construction area of 50000 square meters and annual output value of 500 million RMB.HG group has passed the ISO9001:2008\CE\SGS certificates and has scored more than 300 patents and awards,making it one of the few large-scale private high and new tech enterprise in Shanghai, or even China.

Talking about the structure of the biscuit machine

According to the classification of biscuits, ordinary biscuits can be divided into two categories: crispness and toughness. The small multifunctional biscuit machine is a small production line that can produce these two kinds of biscuit at the same time

  1. Machine structure composition:

Mixer-forming host-drying oven-fuel injector-cooling belt composition

  1. The process flow of the machine:

Raw material pretreatment – dough preparation – rolling out skin – pressing into cake base – baking – oil spraying – cooling – packaging.

  1. Relevant knowledge:

Full automatic Soft & Hard Biscuit Production Line

Full-automatic Soft / Hard / Soda / Beer Biscuit Production Line ( biscuit making machine ) is a new generation advanced equipment which can produce biscuits such as hard biscuit .soft biscuit, soda biscuit, sandwich biscuit, etc. Oven and biscuit making machine shells are all made of stainless steel. This line has the character of big production capacity, Stable running, good-looking surface, easy operation, etc.

The main raw material of biscuits is flour, in addition to sugar, starch, oil, dairy products, eggs, flavors, leavening agents and other auxiliary materials. The above-mentioned raw materials and auxiliary materials are adjusted into dough with a dough mixer, then pressed into dough sheets with a rolling machine, pressed into biscuit blanks with a molding machine, and finally baked in an oven. Turns into crispy and delicious cookies when cooled. Sweet biscuits can be divided into two categories: hard biscuits and crispy biscuits. Whether it is hard biscuits or crispy biscuits, although the recipe, feeding sequence and operation method are different, the basic process is similar.

About the cleaning points of the biscuit sandwich machine

With the continuous expansion of the biscuit sandwich machine market, the types of related machinery and equipment are gradually increasing, so that enterprises can always choose equipment suitable for their own production. More and more biscuit sandwich machine manufacturers have also improved the automation of biscuit production. The biscuit market has an increasing demand for biscuit sandwich machine equipment. Waiyuan Machinery is also making corresponding efforts. By combining the research and development experience and design of advanced equipment, the technical level of the biscuit sandwich machine has been rapidly improved. and reliability, which can better reflect its own advantages in the production of biscuit machines.

The biscuit sandwich machine adopts PLC programmer control system, which encapsulates the electronic components of the body in the electrical box, which can better avoid short circuit of components caused by moisture. At the same time, the biscuit sandwich machine is stable and reliable. There is no hygienic vignetting in the storage compartment of the device. Each position can be cleaned to ensure that the needs and purposes of replacing the filler are met, and one machine can be used for multiple purposes. Taking advantage of the operation of the biscuit sandwich machine, a cleaning system was also added.

After the cleaning operation, the filter material is cleaned and loaded, and the filter material is cleaned by backwashing. Open the water inlet valve, and then open the backwash valve to let in water until the water is clear. When cleaning, be careful not to have a large number of normal filter material particles in the drain pipe, otherwise the water inlet valve should be closed to prevent the filter material from being flushed out.

Soft Biscuit Production Line
Full-automatic Soft / Hard / Soda / Beer Biscuit Production Line ( biscuit making machine ) is a new generation advanced equipment which can produce biscuits such as hard biscuit .soft biscuit, soda biscuit, sandwich biscuit, etc. Oven and biscuit making machine shells are all made of stainless steel. This line has the character of big production capacity, Stable running, good-looking surface, easy operation, etc.

Different choose in the front of the line:

If you want to make a hard biscuit, you need 4 sheeting rollers. hard biscuit forming machine.

If you want to make a soda biscuit, you need to add a pr-sheeter. laminating machine on this basis.

If you want to make soft biscuit,you need a soft biscuit forming machine.

If you want to make a sandwich biscuit, you need to add a biscuit sandwich machine on this basis.

We will design the best scheme and equip the most suitable machine so that you make the most ideal biscuits.
