Description

一种智能多用途液体灭菌机An intelligent multi-purpose liquid sterilizer

技术领域Technical field

本发明涉及饮品安全领域,尤其涉及一种智能多用途液体灭菌机。The invention relates to the field of beverage safety, and in particular to an intelligent multi-purpose liquid sterilizing machine.

背景技术Background technique

传统的液态食品灭菌常采用以下三种灭菌方法:Traditional liquid food sterilization often uses the following three sterilization methods:

巴氏灭菌法(pasteurization),亦称低温消毒法,冷杀菌法,是一种利用较低的温度既可杀死病菌又能保持物品中营养物质风味不变的消毒法,常常被广义地用于定义需要杀死各种病原菌的热处理方法。具体是把液体快速加热到80℃左右,保温20分钟,然后快速冷却。Pasteurization, also known as low-temperature disinfection or cold sterilization, is a disinfection method that uses lower temperatures to kill germs while keeping the flavor of nutrients in items unchanged. It is often referred to in a broad sense. Used to define heat treatment methods required to kill various pathogenic bacteria. Specifically, the liquid is quickly heated to about 80°C, kept warm for 20 minutes, and then quickly cooled.

超巴氏灭菌法,即在原有巴氏灭菌法的基础上,将灭菌温度提高至95-120℃,灭菌时间30-300秒,然后快速冷却。Ultra-pasteurization method is based on the original pasteurization method, increasing the sterilization temperature to 95-120°C, sterilizing time 30-300 seconds, and then rapidly cooling.

超高温瞬时灭菌,超高温杀菌是指将流体或半流体在28s内加热到135~150℃,然后再迅速冷却到30~40℃。目前这种杀菌技术已广泛应用于牛乳、果汁及各种饮料、豆乳茶、酒等产品的生产过程。Ultra-high temperature instant sterilization, ultra-high temperature sterilization refers to heating the fluid or semi-fluid to 135~150℃ within 28 seconds, and then quickly cooling it to 30~40℃. At present, this sterilization technology has been widely used in the production process of milk, juice, various beverages, soy milk tea, wine and other products.

上述三种灭菌方法的灭菌机需要配庞大的锅炉等辅属设备,才能达到灭菌的目的。该灭菌系统的缺点很多:1、投资大;2、占地面积大;3、生产成本高;4、污染环境;5、需大量工作人员;6、生产设备复杂;7、破坏饮品的营养成分和天然风味。The sterilizers for the above three sterilization methods need to be equipped with huge boilers and other auxiliary equipment to achieve the purpose of sterilization. This sterilization system has many disadvantages: 1. Large investment; 2. Large floor area; 3. High production cost; 4. Environmental pollution; 5. Requires a large number of workers; 6. Complex production equipment; 7. Destroys the nutrition of drinks Ingredients and natural flavors.

针对不同的饮品生产企业和不同的食材特性也决定了其适用的灭菌方法。Different beverage production companies and different ingredients characteristics also determine the applicable sterilization methods.

但随着饮品种类的日趋丰富,大众对食品饮品安全的重视,食品饮品安全领域的国家标准、行业标准日趋完善细化,对饮品灭菌工艺及灭菌设备要求更高,灭菌设备分类越来越精细,设备专用性发展趋势愈显突出,相应的设备的研发、使用带来的资源消耗增大,环境污染加剧。如果能够设计一种新型的多用途灭菌装置,实现一机两用,甚至一机多用,一台灭菌机可以实现所有的饮品液体的灭菌,就能够降㡳生产饮品成本、解决高污染带来的不利问题。However, as the types of beverages become increasingly diverse, the public pays more attention to the safety of food and beverages. National standards and industry standards in the field of food and beverage safety are becoming increasingly refined and refined. The requirements for beverage sterilization processes and sterilization equipment are higher, and the classification of sterilization equipment is becoming more and more sophisticated. As the equipment becomes more and more sophisticated, the development trend of equipment specialization becomes more and more prominent. The research and development and use of corresponding equipment will increase resource consumption and intensify environmental pollution. If a new multi-purpose sterilization device can be designed to achieve dual uses in one machine, or even multiple uses in one machine, one sterilizing machine can sterilize all beverage liquids, which can reduce the cost of producing beverages and solve high pollution. adverse problems brought about.
