Description
Technical Field
The invention relates to the technical field of cosmetic manufacturing, in particular to a continuous production system, a continuous production method and application of refined products.
Background
The traditional refined products, including cosmetics, washing products and the like, are currently applied to the traditional intermittent production process on a large scale, and the processing mode has the characteristics of intuitiveness, stage by stage and independent operation. Most of traditional refined products adopt a mixing container (such as a reaction kettle and the like) as a main ingredient mixing processing device, and the simplest flow can be expressed as follows: 1. weighing the components; 2. sequentially adding the components (in a certain sequence) into a mixing container; 3. mixing the mixture in a mixing vessel under certain temperature and pressure conditions for a certain period of time; 4. removing the mixture from the mixing vessel; 5. the mixture is transferred and/or shaped.
However, the main problems of the traditional batch production process are as follows: because the equipment in each stage needs to be operated intermittently in sequence, the unit processing capacity of the equipment is different from the processing technology period, the lowest efficient bottleneck stage can limit the whole technology productivity and the production takt, and the system waste is caused. And the software and hardware of the equipment in each stage are not completely connected with each other, so that data acquisition and quality control are required to be carried out in stages. The problems caused by the two traditional batch processing processes are based on the logic principle of the segmentation process, and can be reduced as much as possible only by the process improvement and the technology improvement, but cannot be completely eliminated.
The above procedures respectively use different processing equipment and adopt intermittent processing technology to realize production. Such as: as the mixing container can contain 7kg of materials at most once, and the weighing device can weigh 5kg at most once and only 0.8kg of finished products is processed, 16kg of materials, 4 times of proportioning, 3 times of mixing and 20 times of molding are needed for producing 20 products. And if there is only 1 product with the possibility of abnormal quality, the feeding needs to be increased and the risks of waste are faced, and the risks aggravate the amount and possibility of waste. And inevitably causes problems such as batch-to-batch quality differences.
Therefore, the traditional intermittent processing technology has the disadvantages in the aspects of process stability and quality stability, chinese patent publication No. CN209718735U discloses a wet powder extrusion device, the function of automatic material pressing is realized through a first material pressing cylinder, materials in a material storage chamber are pressed into a material discharging chamber through a discharging pipe, the materials transmitted into the material discharging chamber are pressed into an extrusion chamber through a second material pressing cylinder, the material blocking function is realized through a second material pressing plate, sealing rings at two ends of the second material pressing plate prevent the materials from escaping to the top of the second material pressing plate, and the conveying function of the materials is realized through a set feeding screw. However, the equipment functions of the equipment are mainly product conveying and compacting, but the equipment does not have mixing processing capability, and the equipment is still a traditional intermittent processing technology per se, so that the problems of the traditional intermittent production technology cannot be solved.
