The main technical means of the patent is that negative pressure is formed by exhausting air in a pulping cavity through steam, and the purpose is to prevent slurry from overflowing; the main technical means of the method is to remove oxygen by exhausting air in the pulping cavity through steam, so as to prevent the prepared pulp from having beany flavor; the two are different.

Example one

A food processor, as shown in fig. 1 and fig. 2, comprises a closed pulping chamber 100 and a steam supply device 200 connected with the pulping chamber 100, wherein the pulping chamber 100 is provided with a normally closed exhaust structure 310 in the pulping stage, and the exhaust structure 310 can be opened and closed.

The application provides a pulping method of a food processor, which comprises the following steps:

and (3) an oxygen removal stage: opening the exhaust structure 310, supplying steam into the pulping chamber 100 by the steam supply device 200, and extruding and exhausting air in the pulping chamber 100 from the exhaust structure 310;

a pulping stage: pulping is performed in the pulping chamber 100.

In the pulping method, steam is supplied into the pulping cavity 100 in the oxygen removing stage, and the steam extrudes and exhausts air in the pulping cavity 100 from the exhaust structure 310; in the pulping stage, pulping is carried out in the pulping cavity 100, because a large amount of oxygen in the pulping cavity 100 is discharged in the oxygen removal stage, little lipoxygenase can contact and react with the oxygen in the pulping process, little substance B is generated, the prepared pulping basically has no beany flavor, and the drinking feeling is good.

Illustratively, in the oxygen removing stage, the steam is supplied in an amount of not less than 0.245V, which is the volume of air in the pulping chamber 100, and the soybean milk produced in the pulping stage by using the above scheme has little beany flavor and does not substantially affect the drinking feeling.

Illustratively, in the oxygen removal stage, the steam is supplied in an amount of not more than 11V. On one hand, the speed of introducing the steam into the pulping cavity 100 is higher than the air exhaust speed of the pulping cavity 100, when the supply amount of the steam is higher than 11V, the pressure in the pulping cavity 100 is too high, and the steam is difficult to be continuously introduced into the pulping cavity 100; on the other hand, when the steam is supplied in an amount of 11V, the air content left in the chamber 100 is very small, and the prepared soybean milk has no beany flavor, and the steam does not need to be continuously supplied, thereby reducing the waste of electric energy.

Illustratively, in the oxygen removing stage, the steam is supplied in an amount of 0.413V-4.95V, so that the air content in the pulping cavity 100 is low during pulping, the prepared pulp has no beany flavor, and the energy consumption is saved.

For example, as shown in fig. 1 and fig. 2, the food processor further includes a heating device 400 and a crushing device 500 disposed at a lower portion of the pulping chamber 100, before pulping, the temperature of water in the pulping chamber 100 is 10 to 90 degrees (the temperature of water added into the pulping chamber 100 may be 10 to 90 degrees, or the temperature of water added into the pulping chamber 100 may be normal temperature water, and the normal temperature water is heated to 10 to 90 degrees by the heating device 400), and the temperature of water in the pulping chamber 100 may be 60 degrees, so that the content of soluble protein in the prepared slurry is ensured to be higher, and the taste and flavor are better; in the pulping stage, the crushing device 500 and the heating device 400 are started to pulp, and the softened bean material is easier to crush. In addition, in the pulping stage, steam in the pulping cavity 100 is cooled to form condensed water, so that the pressure in the pulping cavity 100 is reduced, low-pressure pulping is realized, and the phenomenon that a large amount of pulp bubbles are generated in the pulp in the pulping process and the pulp overflows can be prevented.

The exhaust structure can be a one-way exhaust valve or an electromagnetic valve, and after the steam stops supplying, the exhaust structure is turned off to ensure that the outside air is sucked into the pulping cavity under the action of negative pressure in the pulping stage. Or, the pulping cavity 100 is provided with a water inlet and exhaust valve 300, the water inlet and exhaust valve 300 is provided with a water inlet and exhaust port 320 and an exhaust structure 310, and the steam supply device 200 is connected to the water inlet and exhaust port 320 and is used for supplying water or steam into the pulping cavity 100 and synchronously performing steam inlet and air exhaust. Or, the slurrying cavity is including smashing cup and bowl cover, the bowl cover can open and shut the lid dress on smashing the cup, the sealing member sets up between smashing cup and bowl cover, let in steam in the slurrying cavity and order about the sealing member and warp and form exhaust structure, the air in the slurrying cavity is outwards discharged from exhaust structure, when pressure is less than ambient pressure in the slurrying cavity, atmospheric pressure can extrude the outward flange of sealing member downwards, make the outward flange of sealing member compress tightly sealed on the up end of smashing the cup, the gap can not appear between the up end of sealing member and smashing the cup.

Illustratively, there is also a steam cooling stage between the oxygen removal stage and the pulping stage: cooling the steam in the pulping chamber 100 to reduce the pressure in the pulping chamber 100 to below atmospheric pressure; the food processor also comprises a crushing device 500 arranged at the lower part of the pulping cavity 100, and the crushing device 500 is started to pulp in the pulping stage, so that the pulp in the pulping cavity 100 can be prevented from overflowing. Moreover, after the pulping and boiling are finished, the pressure in the pulping cavity 100 is not very high, and the safety is better.

Illustratively, the volume of the pulping chamber 100 is 300ml to 1600ml, which is suitable for food processing machines of various sizes.

In an exemplary embodiment, as shown in the following table, the volume of the pulping chamber 100 is 500ml, the volume of the material is 300ml, and the amount of steam introduced is 184 ml.

In an exemplary embodiment, as shown in the following table, the volume of the pulping chamber 100 is 1500ml, the volume of the material is 800ml, and the amount of steam introduced is 642 ml.

Data relating steam supply to pressure within the pulping chamber 100 after cooling of the steam:

V2	0.11V	0.245V	0.413V	0.629V	0.917V
						P	P0	0.9P0	0.8P0	0.7P0	0.6P0

						P	0.5P0	0.4P0	0.3P0	0.2P0	0.1P0

the above examples all have a pressure within the pulping chamber 100 of about 0.6 times atmospheric pressure after steam cooling, satisfying the experimental data sheet (in the above table, V₂P is the pressure in the pulping chamber 100 after cooling of the steam, P is the steam supply₀The pressure is outside atmospheric pressure), the slurry can not be raised and overflowed in the pulping process; and, V₂Above 0.245V, the resulting slurry is also substantially free of beany flavor, V₂Between 0.11V and 0.245V, the prepared slurry has less beany flavor.

For example, as shown in fig. 2, the steam supply device 200 includes a water tank, a water pump and a steam generator connected in sequence, the steam generator is further connected to the water inlet 320, and the water pump can also pump normal temperature water or heated water from the steam generator into the pulping chamber 100.

For example, when steam is supplied into the pulping chamber 100, pulping is performed in the pulping chamber 100, that is, the rear stage of the oxygen removal stage and the front stage of the pulping stage are performed simultaneously, and the purpose of the present application can be achieved without departing from the design concept of the present invention, and therefore, the present application is not described herein again and should also fall within the protection scope of the present application.

Exemplarily, the heat dissipation structure is disposed on the outer surface of the cavity 100, and the heat dissipation structure can increase the cooling speed of the steam in the cavity 100, so that the time required by the steam cooling stage is shorter, and the pulping time of the food processor can be better shortened.
