Description

Vacuum food crushing and stirring machine

Technical Field

The invention belongs to the technical field of food processors, and particularly relates to a vacuum food crushing stirrer which crushes and/or stirs food under the condition of vacuumizing.

Background

The food is easy to have enzymatic browning phenomenon due to the contact of fine particles of the food with oxygen in the air or dissolved oxygen in water in the crushing process, so that the nutrition loss of fruits and vegetables and the change of the taste are caused.

The prior art has a vacuum food processor, which comprises a motor, a machine base, a cutter, a vacuum pump, an upper air exhaust path, a lower air exhaust path, a cutter disc and a material cup, wherein the material cup is arranged above the cutter disc, a sealed transmission device cavity is formed between the cutter disc and the machine base, the motor drives the cutter to rotate through a transmission device in the transmission device cavity, the upper end of the upper air exhaust path is communicated with the material cup, the lower end of the upper air exhaust path is communicated with the transmission device cavity, the upper end of the lower air exhaust path is communicated with the transmission device cavity, and the lower end of the lower air exhaust path is communicated with the vacuum pump, therefore, the vacuum pump can provide a vacuum environment for the material cup, the vacuum food processor has obvious defects that the upper end of the upper air exhaust path is required to be positioned above food liquid to avoid the food liquid from being sucked into the air path, so that the upper air exhaust path, the complete machine is small, and the space in the material cup is very limited, adopts this kind of overlength air exhaust gas circuit to be unfavorable for putting into of foodstuff very much to the interference of smashing the foodstuff to the cutter is especially serious, influences the effect that use experience and foodstuff are smashed.

Disclosure of Invention

In view of the above, the present invention provides a vacuum food grinder-blender to solve the above technical problems.

The invention is based on the following research findings of the inventor and is creatively provided with: it is generally accepted by those skilled in the art that the upper end of the upper pumping air path in the vacuum food processor mentioned in the above background should be located above the food liquid. Although the prior art has a gas-permeable and water-impermeable device, and the gas-permeable and water-impermeable device is used for the air extraction opening of the air extraction air passage to prevent liquid from splashing into the air passage, the skilled in the art never considers that the air extraction opening of the air extraction air passage is arranged below the liquid level of the food liquid, because the skilled in the art generally considers that when the air extraction opening of the air extraction air passage is arranged below the liquid level of the food liquid, the air extraction efficiency of the vacuum pump is extremely low due to the liquid sealing effect, so that a meaningful vacuum environment cannot be provided. However, the inventor found that this is not the case, and actually, in the process of crushing foodstuff by rotating the cutter at a high speed, the foodstuff liquid in the cup is in an air-water mixing state under the stirring action of the cutter, the air suction opening of the air suction path is arranged below the liquid level of the foodstuff liquid, and by arranging the air-permeable and water-impermeable device at the end where the air suction opening of the air suction path is located, not only the liquid is not sucked into the air suction path during air suction, but also the air suction efficiency is not affected as seriously as is generally considered.

From this, the inventor has broken through traditional cognition, and the second end (the second end is located the material cup) that will bleed the gas circuit sets up ventilative impervious device and sets up below the liquid level of food liquid for the height of the gas circuit of bleeding in the material cup reduces greatly, thereby has overcome the shortcoming of this type of vacuum food processor among the prior art, and it is better to use experience, washs more easily, and is more firm reliable, can not influence the evacuation crushing effect of foodstuff moreover.
