Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of sterilization equipment, specifically a kind of goat milk powder cleaning sterilization equipment, belong to sterilization equipment technical field. BACKGROUND

[0002] As a high-nutrition-value dairy product, the sterilization process in its production process is crucial to ensure product quality and safety.However, traditional sterilization equipment has many limitations, making it difficult to balance sterilization efficiency and nutrient retention.

[0003] Existing technologies mainly rely on thermal sterilization methods, such as the goat milk powder cleaning steam sterilization equipment disclosed in Patent No. CN209693922U, which uses steam to heat and sterilize the milk powder and uses a vibrating device to increase the contact area between the milk powder and the steam. Although this method can achieve a certain sterilization effect, high-temperature steam can cause a large number of heat-sensitive nutrients (such as immunoglobulins and active probiotics) in the goat milk powder to be inactivated, and the moisture introduced by the steam can cause the milk powder to clump, requiring an additional drying process, increasing energy consumption and process complexity. For example, the goat milk sterilization device disclosed in Patent No. CN102326621A uses a double-pipe heat exchanger to heat the goat milk (to 95°C) and combines high-pressure homogenization for sterilization. This device uses gentle heat exchange and high-pressure homogenization to break down bacillus spores, reducing some vitamin loss (allegedly 4-5%). However, it is still a high-temperature process and cannot completely avoid damage to heat-sensitive components. Moreover, this device is mainly designed for liquid goat milk sterilization, and its sterilization uniformity and anti-caking effect are limited for powdered goat milk. The device structure is complex, and cleaning and maintenance are inconvenient. In addition, the sterilization device for goat milk powder processing in existing technologies attempts to improve heat exchange speed and sterilization effect by setting heating tanks, cooling tanks, and stirring mechanisms, but its core still relies on the principle of thermal sterilization using hot water heating and cold water cooling, which cannot fundamentally solve the problem of thermal damage. Moreover, there is a lack of effective in-situ cleaning means, and the inner wall of the device is prone to residual milk scale after long-term use, posing a risk of cross-contamination.

[0004] In summary, existing goat milk powder sterilization equipment has the following problems: the sterilization method is single, mainly relying on high temperature, leading to severe loss of heat-sensitive nutrients and affecting product nutritional value; sterilization uniformity for powdered materials is insufficient, with potential sterilization dead angles and incomplete sterilization effect; the device lacks an efficient and automated cleaning system, making cleaning inconvenient and prone to cross-contamination, affecting continuous production efficiency and product hygiene and safety.
