Abstract: Zha Pi Brew has always been a favorite drink among consumers. Its consumption has an increasing trend all over the world. In this situation, the disadvantages of the current low efficiency of the cleaning of the barrel cleaning equipment must be increasingly prominent. Based on the analysis of the existing beer cleaning equipment and cleaning methods, a parallel cleaning method based on T910 series PLC of Beijing Teng Control Technology Co., Ltd. was proposed. The structure of the beer cleaning machine was redesigned. Efficiency will increase 3-4 times, which can effectively alleviate the above situation.
Keywords: efficiency; parallel cleaning method; Teng PLC
1 Introduction
Beer is a non-fermented beer. It is a natural, non-pigmented, preservative-free, unsweetened, and unflavored high-quality beverage with high nutritional value. The beer barrel cleaning equipment is developed with the popularity of beer. With the continuous improvement of people’s living standards, the consumption of beer has also been increasing year by year, and the problem of washing beer barrels has also been revealed. Although the current beer cleaning equipment in the barrel has been controlled by PLC, semi-automatic operation has been realized. However, with the further increase in the consumption of beer, the problem of low efficiency in cleaning beer barrels will also gradually become more prominent. This paper proposes a parallel cleaning method based on T910 series PLC of Beijing Teng Control Technology Co., Ltd. and redesigns the structure of the beer barrel cleaning machine, which greatly improves the cleaning efficiency and effectively overcomes the problem of low cleaning efficiency.
2 Current cleaning equipment analysis
2.1 Current cleaning equipment structural features
Typical cleaning equipments, such as various models of washing machines produced by Qingdao Huaying Beer Equipment Co., Ltd., have their cleaning heads fixed on the workbench of the cleaning equipment. When the beer barrel is placed on the cleaning head, the beer barrel is pressed under the pneumatic cylinder installed above the rack so that the cleaning head will open the lid and then perform related operations.
2.2 Current Cleaning Equipment Cleaning Principles
Although the current cleaning equipment manufacturers and product models are all different, the cleaning process is similar. The cleaning process is shown in Figure 1.
Figure 1 Current cleaning equipment cleaning process
Although the current beer-drinking barrel cleaning equipment has strong universality and can clean various types of beer-making beer barrels, its cleaning capacity is only 100-120 barrels per hour, and at least two workers are required to work together, with the increase in the consumption of beer. This kind of cleaning efficiency is relatively low.
3 parallel design of beer cleaning equipment
3.1 Design Principles of Parallel Beer Brew Cleaning Equipment
If this current cleaning method is defined as a tandem cleaning method, the so-called tandem cleaning method means that the cleaning actions are performed sequentially, that is, when the beer bin is installed, the cleaning process sequence is performed according to FIG. 1 , and then the unloading is stopped. What is proposed and adopted here is a parallel cleaning method. In the so-called parallel cleaning method, there are five processes in the cleaning process, and five cleaning heads are set to work on five beer barrels simultaneously. After the completion, the five barrels are sequentially changed in position. In this way, when five processes are completed, the five barrels are cleaned. Based on this idea, a new set of parallel-type beer bin cleaning equipment was designed.
3.2 system structure of parallel-type beer barrel cleaning machine
This set of equipment contains a total of three parts: hydraulic system (washing pump system part), electrical control system and mechanical body part. as shown in picture 2.
Figure 2 structure of the cleaning machine system
3.2.1 Washer Hydraulic System Design
The hydraulic system includes a clear water pump, a hot alkali water pump and a sterilized water pump as well as piping and its accessories, as well as pneumatic valves. According to the parallel cleaning method and the requirements of the cleaning process shown in Fig. 1, the hydraulic schematic is designed as shown in Fig. 3.
Figure 3 schematic diagram of the hydraulic system of the washing machine
3.2.2 cleaning machine electrical system design
The electrical system uses the Teng Control PLC as its core, including Teng Control T910 PLC, solenoid valve, photoelectric sensor, AC contactor, and motor to achieve electrical control of the gas, thereby controlling the gas, electricity and liquid of the gas or gas control fluid to control each other. Electrical control method.
Four switching inputs and five switching outputs are required in this electrical system. Teng control T910 has 12 digital inputs and 8 digital outputs to meet the basic IO requirements. At the same time, T910 can adapt to different harsh environments, with a wider temperature range. Figure 4 is a T910 wiring diagram.

3.2.3 innovative design of mechanical body cleaner
The mechanical body part (see Fig. 5) mainly includes a rotary table, a cleaning head part, a frame, and a drive motor. The rotary table is composed of a bucket holder and a bucket support bracket, wherein the bucket holder is used to fix the beer bucket, and the bucket holder is used to fix the 6 bucket holders and is uniformly distributed at 360°. The cleaning head consists of five cleaning heads and a cleaning head bracket. The bracket is in a ring shape, five cleaning heads are bolted to the cleaning head bracket by 60°, and the other 60° position is empty. Make and unload beer buckets for non-stop production. The motor is connected to the rotary table via the coupling and the drive shaft.

3.3 Working Process of Parallel-type Beer Drum Cleaning Equipment
As shown in FIG. 5, the cleaning apparatus is provided with six stations, which are empty spaces, row of residual wine, clean water in and out, hot and alkaline water in and out, disinfectant water in and out, carbon dioxide back pressure. When all six barrels are pressed on the rotary table, the start button is pressed and the motor drives the rotary table to rotate. When the beer bin cover is aligned with the cleaning head, the sensor detects the position and the motor stops and starts from It takes 0.5-1 seconds to detect the correct position. After the barrel is aligned with the cleaning head, ie, the motor is stopped, the air cylinder pushes the cleaning head carriage to drive the five cleaning heads to rise simultaneously. The rise time is 0.5-1 second, and the cleaning head performs operations on five barrels at the same time (except for the empty seats). barrel). Cleaning head 1 gas flushing residual wine, takes 4 seconds; cleaning head 2 high pressure water flush 4 seconds, air flushing drainage 7 seconds; cleaning head 3 high pressure hot alkaline water 3 seconds, gas flushing hot alkaline water 6 seconds; cleaning head 4 High pressure into the disinfectant 4 seconds gas flushing disinfectant 7 seconds; the cleaning head 5 carbon dioxide back pressure takes 6 seconds, so the longest time for these 5 cleaning heads is 4 seconds plus 7 seconds for 11 seconds, that is, the public cycle is 11 second. After 11 seconds, the cleaning head needs 0.5-1 second to decelerate. After the cleaning head is lowered, the motor drives the rotary table to rotate by 60°. This is detected by the sensor. This takes 0.5-1 seconds, so the time for cleaning a barrel is 18-20 seconds. The cleaning device can wash 180-200 barrels per hour.
4 Conclusion
This article adopts Beijing Teng Control T910 series PLC to redesign the current beer-making barrel cleaning machine and proposes a parallel cleaning method. The maximum efficiency ratio of the parallel-connected beer barrel cleaning machine and the current cleaning equipment is 200/120. If the number of workers is the same and the hours of work are the same, the clear efficiency of the parallel-type beer bin washing machine will be 3-4 times higher than the current one, which effectively relieves the current low efficiency of the beer cleaning equipment.
