Description

Technical Field

[0001] The utility model relates to the technical field of corn wet grinding, in particular to a corn soaking system for a starch workshop. Background Art

[0002] Corn starch production mainly adopts the corn wet milling process, which takes advantage of the insoluble nature of starch and uses water as the medium to separate the components according to their specific gravity and shape through processes such as soaking, grinding, screening, separation, washing, dehydration and drying. The corn wet milling process can almost completely separate the components such as starch, protein, germ and fiber.

[0003] In the corn soaking process, the existing soaking methods are mostly static soaking, steam heating to increase the temperature, and the waste heat from subsequent drying of fiber, germ and protein cannot be utilized. Utility Model Content

[0004] In view of this, the utility model discloses a corn soaking system for a starch workshop, which makes full use of waste heat, saves steam and improves production efficiency.

[0005] Based on the above purpose, the technical solution provided by the utility model is:

[0006] A corn soaking system for a starch workshop, comprising a soaking tank and a circulation pipe;

[0007] The soaking tank is provided in plurality, and the plurality of soaking tanks are cascaded;

[0008] Each soaking tank is provided with a feed inlet at the top and a discharge port at the bottom; a liquid pipe is provided at the upper part of the side wall of the soaking tank, and a swirl liquid inlet pipe and a swirl liquid outlet pipe are provided at the lower part of the side wall; the swirl liquid outlet pipe of the soaking tank is divided into two paths through a circulation pipe, which are respectively connected to the liquid pipe of the soaking tank of the current level and the swirl liquid inlet pipe of the next level;

[0009] The cyclone liquid inlet pipe of the first-stage soaking tank is connected to the sulfite storage tank, and a new acid pump and a new acid heater are provided on the connecting pipe between the two; the circulation pipe of the final-stage soaking tank is divided into two routes, which are respectively connected to the liquid pipe of the soaking tank of this stage and the waste acid pool;

[0010] The main pipe of the circulation pipe is provided with a circulation pump and a circulation heater.

[0011] Furthermore, the number of the soaking tanks is at least three.

[0012] Furthermore, the circulation heater and the new acid heater are both heat exchangers; the waste heat heats the circulation pipe through the heat exchanger.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] The utility model heats the acid through a heat exchanger, so that the waste heat is fully utilized. Compared with the steam in the prior art, the production efficiency is improved and the burden on the enterprise is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the structure of an embodiment of the utility model.

[0016] In the figure: 1. new acid pump, 2. new acid heater, 3. circulation pump, 4. circulation heater. DETAILED DESCRIPTION

[0017] In order to facilitate technical personnel in this field to understand the technical solution of this patent, and at the same time, to make the technical purpose, technical solution and beneficial effects of this patent clearer and to fully support the scope of protection of the claims, the technical solution of this patent is further and more detailedly explained in the form of specific cases.

[0018] Reference Figure 1 This embodiment includes a sulfite storage tank, a soaking tank group, a new acid pump, a new acid heater, a circulation heater, and a circulation pump connected by pipelines. The soaking tank group is composed of a plurality of soaking tanks connected in sequence by pipelines, and the waste heat is used to heat the soaking circulation pipe through a heat exchanger.

[0019] A liquid pipe is provided on the upper side wall of the soaking tank, and a feeding port is provided on the top. A swirl liquid inlet pipe, a swirl liquid outlet pipe and a discharge pipe are provided at the lower part of the soaking tank. The sulfite storage tank is connected with the swirl liquid inlet pipe through a pipeline. A new acid pump and a new acid heater are arranged on the pipeline between the sulfite storage tank and the swirl liquid inlet pipe. The swirl liquid outlet pipe is connected with the liquid pipe. A circulation heater and a circulation pump are arranged on the pipeline between the swirl liquid outlet pipe and the liquid pipe. The upper-level circulation pump is connected with the swirl liquid inlet pipe of the lower-level soaking tank through a pipeline.

[0020] The sulfurous acid aqueous solution in the sulfurous acid storage tank is transported to the soaking tank group to soak the corn in countercurrent. The soaking liquid circulates in the soaking tank while being transported to the next soaking tank.
