Description

The automatic soda acid cleaning sterilizing device of milk container and defeated milk equipment

Technical field

This utility model relates to a kind of automatic clearing apparatus of removing milk dirt in milk container and the defeated milk equipment, particularly can mix with the water dilution ratio and cleans by prewashing-alkali cleaning (pickling)-washing-sterilization-cleaning procedure of standard by acid, the alkali liquor set.

Background technology

Can form the precipitation of proteinic deposition and mammary calculus in the milk container of storing milk or sheep milk or the milk flowing pipe road equipment, i.e. the milk dirt.Fat and the albuminous coat removed in the milk dirt need alkaline solution, and the deposition salt in the cleaning milk dirt needs to use acid solution, stores up also easy breed bacteria in the milk equipment in addition, must carry out disinfection.Therefore the cleaning procedure of standard is that pickling and alkali cleaning hocket, and carries out disinfection at last, and wherein acid ﹠ alkali liquid and water must be mixed in proportion with in order to be effective.

At present, most direct-cooling type container for storing milk all is not equipped with soda acid automatically washing and sterilizing device, obviously causes the accumulation of milk dirt and exceeding standard of milk bacterial content easily.The cleaning of part milk container is by manually finishing, and defective is that the mixed and the scavenging period of acid ﹠ alkali liquid is wayward, influences the cleaning performance of equipment, and soda acid and sterilized stock solution splash skin easily in the manually-operated process, and causing stimulates and damage.The large-scale milk processing factory of part is equipped with CIP clean-in-place system milk container is cleaned, and shortcoming is that CIP equipment is very huge, involves great expense, and needs steam, and the pipe-line system complexity.Having similar automatic clearing apparatus to carry out soda acid to small-sized milking machine in addition abroad cleans, shortcoming is that versatility is not strong, can only clean at its supporting milking machine, also has the soda acid container that is equipped with also too small, the cleaning water yield is too small, can't clean relatively large storage milk equipment such as milk containers.

Summary of the invention

For overcome present milk container clean main by craft be difficult to guarantee cleanout fluid by the correct proportions dilution, be difficult to multiple washing liquid and replace cleaning and make the shortcoming of cleaning performance difference; In order to overcome the shortcoming of present CIP purging system equipment bulky systems complexity; Present milking machine washer water yield is little in order to overcome, the versatility difference can only be carried out the shortcoming that supporting cleaning causes cleaning bigger milk container to milker, this utility model provides a kind of milk container is carried out automatic soda acid cleaning and disinfectant device, whole equipment volume of this rinser is less than 1 cubic metre, can set the mixed proportion of soda acid and water, the user presses corresponding button can carry out corresponding pickling program or alkali cleaning, disinfectant program automatically, and liquid outlet quantity reaches 3-4m ³/ h.

The technical scheme that its technical problem that solves this utility model adopts is: dress acid, alkali and sterilization dope in three cylindrical vessels, liquid outlet quantity reaches 3-4m during owing to design ³/ h, correspondingly the container of acid, alkali and disinfectant solution must be enough big, therefore designed sour, alkali container capacity and be not less than 50 liters respectively, and the disinfectant capacity is not less than 20 liters.Container bottom links to each other with three electromagnetic valves by conduit respectively, the other end of three electromagnetic valves links to each other with three terminals of four-way, the remaining end of four-way links to each other with an end of a small-sized flow rotating regulation valve, the other end of control valve links to each other with an end of threeway, the other end of threeway is a water inlet pipe, be equipped with a ball valve on the water inlet pipe with the control inflow, the 3rd end of threeway links to each other with the entrance point of pump, and the delivery side of pump end is sent mixed cleanout fluid pressurization by delivery channel.Ball valve control inflow size on the water inlet pipe, and small-sized flow rotating regulation valve is controlled the flow of concentrated acid alkali liquor, controls both mixed proportions by the flow of regulating water and soda acid disinfectant solution.The profile of whole device is a cuboid, and volume is less than 1 cubic metre.Circuit connects: three power of electromagnetic valve lines link to each other with three relays on the control circuit board respectively, the power line of pump also links to each other with a relay on the circuit control circuit board, make chip with the C51 single-chip microcomputer on the control circuit board, in chronological sequence carry out switch motion by four relays of programming Control, have on the user interface of control circuit the input of three buttons as with the interface of user interactions, represent pickling respectively, alkali cleaning and shutdown, when chip detection when the user presses pickling key or alkali cleaning key, chip is by the relay switch action different with time control of specified order; When carrying out the pickling program, invalid by the alkali cleaning key, vice versa; When chip detection arrived stop key, chip disconnected all relays.Process with pickling is that example is told about detailed process below: when the user presses the pickling button, chip is at first connected the relay of control pump, because three electromagnetic valves are normally closed solenoid valve, the mechanical interface two ends that are electromagnetic valve under the no power situation are cut off, this moment, pump extracted output the carrying out prewashing of water pressurization back, chip is connected the relay of the sour electromagnetic valve of control after three minutes, acid solution flow through four-way by electromagnetic valve and entered threeway this moment, inhale in the vacuum inspiration pump that forms with being pumped after water mixes, send after the pressurization, enter the pickling program this moment, and the relay of chip closing control acid electromagnetic valve is connected the relay of controlling the disinfectant solution electromagnetic valve after ten minutes, enter disinfectant program this moment, the relay of closing control disinfectant solution electromagnetic valve after two minutes, this moment, pump sucked has only water, enters last cleaning procedure, chip disconnects the relay of control pump after five minutes, quit a program, finish pickling, alkaline cleaning procedure in like manner.

The beneficial effects of the utility model are, only need button just can carry out corresponding pickling, alkali cleaning and sterilization to milk container or defeated milk equipment automatically, the mixed solution of ratio preparating acid, alkali liquor and water that can be in accordance with regulations, this utility model volume is little, simple and reliable for structure, the cleaning water yield is big, can carry out soda acid cleaning and sterilization to relatively large milk container and defeated milk equipment.
