Abstract
Description
Technical Field
[0001] This application relates to the field of processing and washing technology, and more specifically, to an energy-saving device for washing corn fiber via enzymatic hydrolysis reaction. Background Technology
[0002] As one of my country's major agricultural products, corn ranks second only to rice in importance, with a wide range of uses covering food, feed, and industry. Internationally, traditional corn starch processing technology generally employs a wet process. This process includes steps such as cleaning impurities, soaking, crushing (including coarse and fine grinding), separation, washing, dehydration, drying, and sieving, ultimately yielding commercial-grade corn starch. It also produces byproducts such as corn germ, corn gluten meal, corn fiber (commonly known as corn husk), and corn steep liquor. The corn starch processing process is often described as "soaking, grinding, and separating," emphasizing three key steps: first, the soaking process is crucial; second, the crushing process (including coarse and fine grinding) must be executed precisely; and third, the fiber washing process requires special attention. Introducing a fiber enzymatic hydrolysis process during the fiber washing stage, by increasing the storage tank capacity to extend the reaction time between the fiber and the compound enzyme preparation, effectively improves the starch yield.
[0003] Existing corn fiber washing devices typically consist of multi-stage fiber washing screens and matching multi-stage fiber washing tanks (usually 6 stages, expandable to 7, 8 or even more stages). However, based on the current state of corn washing treatment, there are still problems of high energy consumption and low efficiency in the corn starch extraction process, which leads to certain limitations in the yield of corn starch.
[0004] To address the aforementioned issues, this application provides an energy-saving device for washing corn fiber via enzymatic hydrolysis. Utility Model Content
[0005] This application provides an energy-saving device for washing corn fiber via enzymatic hydrolysis reaction, comprising multiple sets of screen washing units connected in series. Each set of screen washing units consists of a water injection pipe, a curved screen, and a washing tank. The output end of the curved screen is connected to the input end of the washing tank, and the output end of the washing tank of the previous set of screen washing units is connected to the input end of the curved screen of the next set of screen washing units. The water injection pipe is connected to the washing tank.
[0006] Furthermore, the curved screen includes fiber washing screen one, fiber washing screen two, fiber washing screen three, fiber washing screen four, fiber washing screen five, and fiber washing screen six arranged in sequence.
[0007] Furthermore, the washing tank includes fiber washing tank one, fiber washing tank two, fiber washing tank three, fiber washing tank four, fiber washing tank five, and fiber washing tank six arranged in sequence.
[0008] Furthermore, the screening and washing unit has a six-stage structure, and the total volume of the six washing tanks is twice the hourly fiber slurry delivery rate.
[0009] Furthermore, each of the washing tanks is externally connected to a washing pump via a pipe, and the washing pumps include fiber washing pump one, fiber washing pump two, fiber washing pump three, fiber washing pump four, fiber washing pump five, and fiber washing pump six arranged in sequence.
[0010] Furthermore, the curved sieve is externally connected to an enzymatic hydrolysis reaction tank.
[0011] In summary, this application includes the following beneficial technical effects:
[0012] In this application, an enzymatic hydrolysis reaction tank is used instead of a traditional enzymatic hydrolysis reaction vessel, eliminating the stirring device. The material is fed out first-in-first-out through the liquid level difference, which effectively reduces the mixing of materials. This not only improves the washing efficiency and enhances the washing effect of the material in the washing tank, but also helps to save energy consumption.
[0013] The enzymatic hydrolysis reactor described in this application can be improved by increasing the proportion of enzyme preparations added to the reactor, thereby enhancing the enzymatic hydrolysis effect. This allows corn fiber to fully release the starch and corn protein bound to it, thereby increasing the yield of corn starch. Attached Figure Description

[0020] Example:
[0021] This application discloses an energy-saving device for washing corn fiber via enzymatic hydrolysis. Please refer to [link to relevant documentation]. Figure 1 It includes multiple sets of screen washing units connected in series. Each set of screen washing units consists of a water injection pipe, a curved screen and a washing tank. The output end of the curved screen is connected to the input end of the washing tank, and the output end of the washing tank of the previous set of screen washing units is connected to the input end of the curved screen of the next set of screen washing units. The water injection pipe is connected to the washing tank.
[0022] The curved screen includes fiber washing screen one X110-1, fiber washing screen two X110-2, fiber washing screen three X110-3, fiber washing screen four X110-4, fiber washing screen five X110-5, and fiber washing screen six X110-6 arranged in sequence.
[0023] The washing tanks include fiber washing tank 1 V110-1, fiber washing tank 2 V110-2, fiber washing tank 3 V110-3, fiber washing tank 4 V110-4, fiber washing tank 5 V110-5, and fiber washing tank 6 V110-6 arranged in sequence.
[0024] The screening and washing unit has a six-stage structure, and the total volume of the six washing tanks is twice the hourly fiber slurry delivery capacity.
[0025] Each washing tank is connected to a washing pump via a pipe, and the washing pumps include fiber washing pump 1 P109-1, fiber washing pump 2 P109-2, fiber washing pump 3 P109-3, fiber washing pump 4 P109-4, fiber washing pump 5 P109-5, and fiber washing pump 6 P109-6 arranged in sequence.
[0026] The external connection of the curved sieve is provided with an enzymatic hydrolysis reaction tank V111.
[0027] The enzymatic hydrolysis reaction tank V111 used in this application replaces the traditional enzymatic hydrolysis reaction vessel and removes the stirring device, thereby reducing energy consumption. Furthermore, by using the material liquid level differential pressure, the first-in-first-out (FIFO) principle is achieved, allowing the fiber slurry to flow uniformly and progressively, thus improving the enzymatic hydrolysis efficiency. This effectively reduces the mixing problem of materials during the flow process and ensures that materials can be input and output in a predetermined order. This improvement makes the reaction of materials in the enzymatic hydrolysis reaction tank V111 more complete, thereby improving the efficiency of the reaction and washing process.
[0028] Furthermore, the V111 enzymatic hydrolysis reactor is an improvement and optimization based on the traditional enzyme preparation reaction tank process. This improvement significantly reduces equipment manufacturing investment and saves energy consumption, while ensuring the first-in, first-out principle of materials. The total capacity of the V111 enzymatic hydrolysis reactor is designed to be 1.5 to 2 times the flow rate of the washing pump. Through process adjustment, the reaction time can be maintained at 2 to 2.5 hours or more. In addition, the enhanced uniform washing effect is conducive to the perfect enzymatic hydrolysis reaction, effectively reducing the starch binding content in the fiber, thereby increasing the starch yield, reducing the moisture content of the wet fiber after dehydration, and reducing the amount of washing water used.
[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
