Embodiment Construction
[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, and the implementation scope of the present invention is not limited thereto.
[0038] Such as Figure 1 to Figure 13 Shown, the production technique of the aseptic bean curd of a kind of production equipment described in the present embodiment is characterized in that:
[0039] Step 1: Soybean collection and storage: The factory inspects the soybean raw materials sent to the workshop, and the raw milk that meets the standards is sent to the raw material warehouse for standby after stone removal and impurity removal;
[0040] Step 2: Soybean processing: Dehulling and degerming the soybeans, and then passing the dehulled and degermed raw materials into hot steam at 170°C for 1-3 seconds;
[0041] Step 3: Refining: add hot water 5 times the weight of the raw material, the temperature of the hot water is: 55-60°C, and refine the raw mater...

The invention discloses a production equipment and a production process of sterile bean curd, and the production process comprises the following steps: collecting and storing soybeans, treating soybeans, refining, and separating soybean milk from soybean dregs: separating the materials from a refiner through double-path horizontal centrifugal equipment to obtain soybean milk and soybean dregs; adding hot water into the soybean dregs, carrying out degassing treatment and ultra-high-temperature sterilization, and cooling: heating the soybean milk to 65-75 DEG C through a heat exchanger, carrying out degassing treatment in a degassing unit, transporting the degassed soybean milk into an ultra-high-temperature sterilization system through a conveying pump, and conveying to a sterile filling machine system through a sterile pipeline; aseptically adding a coagulator online: adding the coagulator into the soybean milk subjected to ultra-high-temperature sterilization online on a pipeline in front of a sterile filling machine system, aseptic filling, heating, cooling and storage: transporting the filled product into a sterilization tunnel, controlling the temperature of the sterilization tunnel to be 90+ / -1 DEG C, conveying the product for 50-60 min in the sterilization tunnel, then transporting the product into a cooling tunnel to reduce the product temperature to 25 DEG C. Through the process, the quality guarantee period can be remarkably prolonged.
Description
technical field [0001] The invention relates to production equipment and a production process of aseptic tofu. Background technique [0002] At present, domestic tofu is not individually packaged or boxed, and it is stored and transported in a low-temperature cold chain. The product has a short shelf life and a small sales radius. The most important thing is that it is easy to deteriorate; The finely ground material is subjected to solid-liquid separation to obtain soybean milk and bean dregs. Then, add hot water to the bean dregs again for uniform mixing and then pass through a horizontal centrifuge for solid-liquid separation. The soymilk obtained for the second time is evenly mixed with the soymilk obtained for the first time to increase the protein rate. Okara can be used as poultry feed. [0003] The above-mentioned solid-liquid separation process using a horizontal centrifuge requires two sets of horizontal centrifuges, resulting in increased tofu production costs an...
