[0024] Example 1

[0025] like Figure 1 As shown, the present invention proposes a simulation device for evaluating the cleaning effect of a CIP cleaning agent, comprising:

[0026] A water bath 1 contains liquid and is maintained at a temperature by a heating device, the temperature of which is set according to actual needs;

[0027] The liquid reservoir 2 is provided in the water bath 1 and stores detergent. The detergent concentration in the liquid reservoir 2 is controlled by an external detergent feeding device and is provided with a concentration detection device.

[0028] A circulation mechanism draws the cleaning agent out of the liquid storage tank 2 to form a circulation route and then flows into the liquid storage tank 2;

[0029] and a simulated pipeline 8 , which is arranged in a cleaning agent circulation flow route, through which the cleaning agent flows, and inside which the dirt is coated.

[0030] Example 2

[0031] like Figure 1 As shown, the present invention proposes a simulation device for evaluating the cleaning effect of a CIP cleaning agent. Compared with the first embodiment, this embodiment introduces relevant details.

[0032] A thermometer 4 for detecting the temperature of the detergent is provided in the liquid reservoir 2. The thermometer 4 is a digital thermometer. Specifically, the detection rod of the thermometer 4 is inserted below the detergent liquid level in the liquid reservoir 2, and the digital display end of the thermometer is located above the liquid reservoir 2. The liquid temperature in the water bath 1 is adjusted according to the displayed value of the thermometer 4. When the thermometer 4 detects that the temperature of the detergent has not reached the use temperature, the liquid temperature in the water bath 1 is increased. Conversely, when the thermometer 4 detects that the temperature of the detergent is higher than the use temperature, the liquid temperature in the water bath 1 is lowered.

[0033] The circulating flow mechanism includes a water pump 3 arranged in the liquid storage tank 2, a liquid outlet pipe 5 connected to the output end of the water pump, and a liquid return pipe 9 with its end inserted into the liquid storage tank 2. The two ends of the simulation pipeline 8 are connected to the liquid outlet pipe 5 and the liquid return pipe 9 at the same time. Stains are coated on the inner wall of the simulation pipeline 8 to detect the cleaning effect of the detergent. The liquid outlet pipe 5, the simulation pipeline 8 and the liquid return pipe 9 form a circulating flow route. The material of the simulation pipeline 8 is a transparent glass tube, a transparent plastic tube or a 304 or 316 stainless steel tube. When using 304 or 316 stainless steel tubes, an industrial endoscope is set on the 304 or 316 stainless steel tube to facilitate observation of the cleaning effect.

[0034] Both ends of the simulation pipeline 8 are connected to the liquid outlet pipe 5 and the liquid return pipe 9 through a joint 7. In an optional embodiment, the joint 7 is a connecting flange, that is, the ends of the liquid outlet pipe 5 and the liquid return pipe 9, as well as both ends of the simulation pipeline 8, are provided with connecting flanges.

[0035] The liquid return pipe 9 is a rubber tube or a silicone tube; the liquid outlet pipe 5 is provided with a flow meter 6, which is a digital flow meter.

[0036] In summary, to use the present invention, the desired stain is applied to the simulated pipe 8 according to the experimental purpose, and the connector 7 is connected. The CIP cleaning agent to be evaluated is then diluted to the desired concentration and placed in the reservoir 2. The constant-temperature water bath 1 is then heated to the desired temperature. The water pump 3 is then turned on and adjusted to the desired flow rate, and a timer is started until the desired cycle time has elapsed. The cleaning performance of the CIP cleaning agent can be evaluated by observing the stain removal in the simulated pipe 8 or by sampling the reservoir 2 to detect microbial growth. The water bath 1 controls the temperature, and the flow meter 6 controls the flow rate. The time element is controlled by the cycle timer, the concentration is controlled by externally dispensing the cleaning agent into the reservoir 2, and the medium element is controlled by changing different cleaning agents. This completes the control of the five elements of CIP cleaning: temperature, time, flow rate, concentration, and medium, simulating actual cleaning. The cleaning performance can be evaluated by observing the transparent simulated pipe 8 coated with the stain. The total bacterial count in the liquid in the reservoir 2 can also be tested to assess the sterilization and disinfection efficacy.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
