Description

Food processor with electronic aspiration pump

Technical field

The utility model relates to a kind of food processor with electronic aspiration pump.

Background technology

Commercially available food processor comprises positive displacement food processor and the on-positive displacement food processor that can pulverize foodstuff.The positive displacement food processor comprises the positive displacement food processor of soy bean milk making machine, rice paste machine, Juice machine, cooking machine, mixer and other pulverizing foodstuff.The on-positive displacement food processor comprises handheld stirring machine, desk-top mixer, vertical mixer.Its common ground of positive displacement food processor is that a staving and a crushing knife tool device that holds foodstuff is arranged, and it is divided into (like soy bean milk making machine, the rice paste machine etc.) of band heater again and not with two types of heater.Itself does not hold the staving of foodstuff the on-positive displacement food processor, and it only has a motor driven comminution knife tool device, need stretch in other container that is contained with foodstuff and pulverize foodstuff, can be divided into the band heater and not be with heater.

The positive displacement food processor with heater only is not simple pulverizes foodstuff (like meat, beans, five cereals, fruit, vegetables, solid seasoning and so on), and ordinary practice is called cooking machine, fruit juice mixer, mixer etc.; The food processor of band heater is both to pulverize foodstuff, and has electrical heating (electrothermal tube, Electric radiant Heating Film, electromagnetic heater etc.) device to foodstuff heating, boiling, is commonly referred to soy bean milk making machine, rice paste machine, fruits and vegetables machine etc.Novel having concurrently pulverized setting that can also be through control program with the soy bean milk making machine of heating function device, rice paste machine and selected, like simple pulverizing, function such as heat, not only pulverize but also heat merely.

Food processor is provided with the position according to (crushing knife tool device) motor and can be divided into: provided with motor at lower formula, motor overhead, side-mounted three macrotaxonomies of motor:

The staving of provided with motor at lower formula, crushing knife tool device etc. are arranged on above the motor, and it is subdivided into integral type and split type two kinds again.Split type is that motor is arranged in the support, and staving (crushing knife tool device) is arranged on the support top, is dismountable minute body structure between staving and the support.Integral type is that support and staving are one, and staving can not disassemble from support.

The staving of motor overhead (the on-positive displacement food processor does not have staving), crushing knife tool device are arranged on the motor below.

The side-mounted staving (the on-positive displacement food processor does not have staving) of motor, crushing knife tool device etc. are arranged on a side of motor.Horizontal or perpendicular the putting of motor shaft directly or through transfer device stretched in the staving.

The above-mentioned foodstuff crushing knife tool device that all relates to.The effect one of crushing knife tool device is to pulverize foodstuff; The 2nd, stir, mix, foodstuff is overturn in container (staving), make pulverizing more thorough.Pulverizing foodstuff is through the rotation of driven by motor crushing knife tool device, and foodstuff is pulverized, and makes the foodstuff motion simultaneously, reaches abundant pulverizing, purpose of mixing.But the crushing knife tool device of crushing process high speed rotation can produce violent whirlpool in staving, sucks the air in the staving, above the foodstuff liquid level and be air bubble-shaped to be mixed in the foodstuff liquid.Because the air of sneaking in the foodstuff liquid is swiftly flowing; Foodstuff liquid itself is also at high-speed motion; Both strong relative motions cause mixing, rubbing action to small granular foodstuff (foodstuff is from big block the pulverizing to behind the particulate, and its surface area increases thousands of times) especially fruit, vegetables produce strongly, oxidation fast.For example the mixture of apple and water by in the crushing process, only needs 2～5 minutes in food processor, and its foodstuff liquid (fruit juice) color relation (is called enzymatic browning by the pale yellow brown that is oxidized in the biology.Enzymatic browning is under the condition of aerobic, and phenolase catalysis aldehydes matter forms the course of reaction of quinone and polymer thereof), mouthfeel is variation also.And foodstuff liquid only is that foodstuff liquid surface contacts with non-moving air in inactive state, and its oxidation to foodstuff liquid is just very slow.

Present commercially available positive displacement food processor, staving top has lid (head of motor overhead itself serves as the lid of staving), and the problem of its existence is: 1, lid blow-by; 2, food processor need not made bucketful foodstuff liquid such as fruit juice (simultaneously because lid does not seal yet when the overwhelming majority uses; If fill fully; Foodstuff also can overflow when pulverize stirring), this not only makes has a large amount of air and this air communicates with outside atmosphere in the bucket.The on-positive displacement food processor then normally stretches in other open containers and pulverizes foodstuff, and foodstuff is directly exposed in the air especially.In crushing process, foodstuff liquid whirlpool can not only suck the air of top in the staving thus, also can further suck the outer air of staving, and foodstuff liquid is produced fast significantly oxidation.

The oxidation of foodstuff is divided into three links in the common food processor: before foodstuff was pulverized, in the crushing process and pulverizing finish.(being the normality of foodstuff) was big block object (a for example whole apple or apple piece) before foodstuff was pulverized, and oxidation generally only limits to surface (within the several hrs) and because of surface area is little, oxidation deterioration is very slow usually.Foodstuff is pulverized after finish (promptly make and be fruit juice); Being placed on staving (or pouring in the cup) is inactive state; No longer carry out vigorous stirring also no longer with the air strong friction, so (within the several hrs) oxidation only limits to the fruit juice top layer of inactive state, oxidation is also not obvious on the whole.Only in the foodstuff crushing process; Foodstuff liquid contacts and violent friction with the air large tracts of land that (being inhaled into) is blended in wherein; Oxidation is the most outstanding and strong, and its oxidation effectiveness of 2～3 minutes is all significantly more than 2～3 hours oxidation effectiveness of other two links.In addition, the rising of foodstuff liquid temp also is the key factor of accelerated oxidation.No matter but the oxidation of which kind of mode, its prerequisite is: foodstuff must contact with abundant oxygen, otherwise does not have oxidation.
