Technical Field

The invention relates to the field of automatic metering, in particular to a monoglyceride automatic metering system;

the invention relates to the field of automatic metering, in particular to automatic metering equipment for monoglyceride.

Background

The metering pump is a special volumetric pump which can meet the requirements of various strict process flows, can realize stepless regulation of the flow rate within the range of 0-100 percent and is used for conveying liquid (particularly corrosive liquid).

Metering pumps are one type of fluid delivery machine that are characterized by the ability to maintain a constant flow rate independent of discharge pressure. The metering pump can simultaneously complete the functions of conveying, metering and adjusting, thereby simplifying the production process flow. By using a plurality of metering pumps, several media can be input into the process flow according to an accurate proportion for mixing. Due to its own prominence, metering pumps are now widely used in various industrial fields such as petrochemical industry, pharmaceutical industry, food industry, and the like.

The application range of the automatic metering equipment and the metering system of the invention is as follows: in theory, the single grease pump is used in all industries of metering pumps, including the pearl wool industry. The invention takes the single grease pump in the pearl wool industry as an example for detailed description.

In the pearl wool industry, monoglyceride is an extremely important main auxiliary material.

Structure of monoglyceride: the molecular formula is as follows: C21H42O 4; molecular weight 358.87; melting point: 55-60 ℃;

II, the standard of monoglyceride: food additive national standard GB 15612-1995;

third, introduction of monoglyceride: glyceryl Monostearate (GMS) produced by taking natural vegetable oil as a raw material, abbreviated as monoglyceride, has the effective component of more than 90 percent after being purified by a molecular distillation technology, is also called molecular distillation monoglyceride, is a widely applied food additive, is safely used in the production and processing of food, medicine, plastics and the like, and accounts for more than half of the using amount of a market emulsifier.

In the molecular distillation monoglyceride, the content of monoglyceride monostearate with an emulsifying effect is higher, impurities with reduced efficiency are removed, so that the emulsifying capacity is improved by 3-4 times compared with that of crude grease, the addition of 0.05-2% of monoglyceride can meet the processing requirements of products such as food and the like, and the monoglyceride has the characteristics of white color, no smell and stable performance.

Fourthly, the function of monoglyceride in the production of pearl wool:

1. antistatic: the antistatic agent can migrate in plastic resin quickly, has long effect time, can reduce surface resistance, reduce static electricity formation and accumulation, has the functions of quickly and long-acting antistatic and dust adsorption reduction, and is used as an antistatic agent and a dustproof agent in plastic.

2. Excellent emulsibility: the foaming agent can make the foam structure uniform and fine, reduce the shrinkage of the bubbles, particularly has strong anti-shrinkage capability at low temperature in winter, make the product bright and smooth, save raw materials and be used as an anti-shrinkage agent of the auxiliary foaming agent.

3. Lubrication and no abrasion to the screw.

Fifthly, the addition proportion of the monoglyceride is 1.2-1.8% (using amount of the monoglyceride/finished product), and the adverse effect of the monoglyceride is abnormal:

1. too much addition: excessive foaming is excessive and easy to foam. Foaming is a phenomenon that is theoretically expressed as cell coalescence, and many cells coalesce together and become large bubbles, which is what we often say foaming.

Physical appearance of the product with excess monoglyceride: hard and brittle. Interpretation: the melting point of the monoglyceride is 55-50 ℃, the sheet material is converted into a solid state after being cooled, and the single sheet material still changes in a period of time after being made, and the essential reason is that internal stress exists in a molecular structure, the molecular chain is broken due to too fast change, and the phenomenon of foaming is caused due to gas aggregation at the broken part.

2. Too little addition:

2.1, influence on product quality: sheet shrinkage, cell collapse, poor foaming, poor elasticity.

2.2, the influence on safety, static electricity increase, increase the risk of catching fire, cause the conflagration.

Sixthly, the current situation and error area in the use of monoglyceride

1. As a means of temperature control over the process.

2. The oil content of the material is sensed by experience, and the concept of the upper limit and the lower limit is not strong.

3. When the single grease equipment does not work normally, for example, the single grease equipment cannot be driven when the single grease equipment is started, and when the single grease equipment is abnormal in a working state, the abnormity is found to lag behind, so that direct economic loss and safety risk are caused.

The existing metering pump and single glyceride conveying system has no content display equipment capable of visually reflecting the proportion of the conveyed liquid in the product when in use, the process cannot be accurately digitalized, so that the early warning cannot be given when the input of the metering pump system is abnormal, the timely reaction cannot be carried out, the production process is interrupted, and the safety problem is easily caused.
