[0026] A spring piston structure is provided inside the existing steam cooker, which can act as a check valve to prevent starch from flowing back into the steam pipe. The spring piston can move up and down to act as a check valve. However, the spring is easy to break and cannot withstand the pressure of the steam. At the same time, when the steam cooker stops taking in air, the piston moves upward to discharge the accumulated material inside the steam cooker from the holes of the steaming head to prevent the holes of the steaming head from being blocked. However, the cleaning effect is not good, so the holes are often blocked.
[0027] Therefore, how to avoid the spring from being easily broken and the hole from being frequently blocked in the prior art is one of the important problems to be solved in the art.
[0028] Based on this, in view of the above problems, the purpose of the present invention is to provide a starch cooker and system to solve the problems in the prior art that the spring is easily broken and the holes are often blocked.
[0029] Figure 1 The structure diagram of the starch cooker of the exemplary embodiment of the utility model is shown. Figure 2 A system diagram of a starch cooking system according to an exemplary embodiment of the present invention is shown, Figure 1-Figure 2 As shown, the starch cooker provided by the exemplary embodiment of the utility model includes: a barrel 102 and a cooking head 101, the cooking head 101 is arranged in the barrel 102, the barrel 102 has a steam inlet 103, a feed inlet 104, a discharge port 106 and a sewage outlet 105, the steam inlet 103 is connected to the steam tank through an air inlet pipe, the steam flowing into the barrel 102 is used to blow off the starch on the cooking head 101, the discharge port 106 is connected to the starch preparation tank through a feed pipe, the discharge port 106 is connected to the starch cooking tank through a discharge pipe, and the sewage outlet 105 is connected to the sewage tank through a sewage pipe.
[0030] In practical applications, in the starch cooker provided by the utility model, the cooking head 101 is arranged in the cylinder 102, and the cylinder 102 has a steam inlet 103, a feed port 104, a discharge port 106 and a sewage outlet 105. The steam inlet 103 is connected to the steam tank through an air inlet pipe, and the steam flowing into the cylinder 102 is used to blow away the starch on the cooking head 101, the discharge port 106 is connected to the starch preparation tank through a feed pipe, the discharge port 106 is connected to the starch cooking tank through a discharge pipe, and the sewage outlet 105 is connected to the sewage tank through a sewage pipe. On this basis, the spring in the cylinder 102 of the starch cooker is removed, and the steam in the steam tank is used to blow away the starch on the cooking head 101. At the same time, the original piston structure is welded to the bottom of the cooker and replaced with the discharge port 106 and the sewage outlet 105. While avoiding the clogging of the cooking head 101, there is no need to replace the spring, which effectively solves the problem that the spring is easy to break and the holes are often blocked in the prior art.
[0031] For example, Figure 1 As shown, the cooking head 101 also has a feed inlet 104, and the feed inlet 104 of the cooking head 101 is connected to the feed inlet 104 of the digester. On this basis, in order to ensure that starch can smoothly enter the cooking head 101, the diameter of the feed inlet 104 of the cooking head 101 is smaller than the diameter of the feed inlet 104 of the digester. It can be understood that the diameter of the feed inlet 104 of the digester is d1, and the diameter of the feed inlet 104 of the cooking head 101 is d2. Figure 1 It can be seen that d2>d1. In order to ensure the sealing between the feed inlet 104 of the cooking head 101 and the feed inlet 104 of the digester, a sealing member such as a sealing gasket, for example, an O-ring, is provided between the feed inlet 104 of the cooking head 101 and the feed inlet 104 of the digester.
[0032] For example, Figure 1 As shown, the cooking head 101 is a hollow structure cooking head 101. The starch is processed again inside the cooking head 101. Therefore, the cooking head 101 needs to provide a processing space for starch processing. The cooking head 101 is designed as a hollow structure cooking head 101, which is convenient for processing and also reduces the processing cost of the cooking head 101.
[0033] For example, Figure 1 As shown, the side wall of the hollow structure cooking head 101 has a plurality of holes. It can be understood that the aperture of each of the holes is the same. Setting the apertures of the holes to be the same can ensure that the hollow structure cooking head 101 is subjected to uniform force, so that the cooking head 101 is subjected to uniform force in the closed cooking vessel, thereby avoiding the problem of deformation of the cooking head 101 caused by uneven force on the cooking head 101.
[0034] Exemplarily, the above-mentioned barrel 102 is a cylindrical barrel 102, and can also be a barrel 102 of other shapes, which will not be described in detail here. Taking the cylindrical barrel 102 as an example, the cylindrical barrel 102 has uniform force, which can effectively ensure the internal and external force balance of the digester barrel 102, and avoid the problem of deformation of the digester barrel 102 caused by uneven force on the digester barrel 102.
[0035] The exemplary embodiment of the present utility model further provides a starch cooking system, comprising the above-mentioned starch cooker.
[0036] Compared with the prior art, the starch cooking system provided by the present invention has the same beneficial effects as the starch cooker, which will not be described in detail here.
[0037] Exemplarily, the starch cooking system further includes a first switch valve 107, which is disposed on an air inlet pipe connecting the steam inlet 103 of the cylinder 102 with the steam tank, and is used to prevent steam backflow.
[0038] In actual application, the first switch valve 107 is an electric switch valve, which is controlled by some simple electronic control logic. The first switch valve 107 is used to backwash the cooking head 101 in the cylinder 102, and the holes are purged by steam. The holes are thoroughly cleaned under high temperature and high pressure to avoid blockage of the holes. At the same time, the first switch valve 107 can prevent starch from flowing back into the steam tank with the steam.
[0039] Exemplarily, the starch cooking system further includes a first pressure pump 108, which is disposed on a feed pipe connecting the discharge port 106 of the cylinder 102 and the starch preparation tank, and is used to transport starch to the starch cooker.
[0040] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
