Traditionally, the coffee preparer uses coffee bean or powder when brewed coffee, according to the knowledge of the applicant, does not adopt instant coffee as yet in the coffee preparer.Soluble coffee can not be used in the espresso machine in the past, and this is because the cause of the method for operating of espresso machine.It not is soluble coffee that coffee bean or coffee powder in the industry cycle are considered to, and its reason is that powder can not be dissolved in the water very soon.Instant coffee is described to soluble coffee.Traditionally, soluble coffee is not used in the coffee preparer as yet, and this is because the otherwise effective technique that still is unrealized is not developed suitable equipment yet, produces the coffee of this grade by preparer.If in traditional espresso machine, use instant coffee, so, will form out of use unsetting agglomerated coffee.In traditional espresso machine, coffee powder bears steam under pressure, the flavour of squeezing out from coffee powder.Powder can bear steam, still, since the physical property of soluble coffee, the known machines that the steam pressure that must cause substantial variations can not be used to distribute soluble coffee.
There is following demand, that is, and to provide the coffee that reaches the brewed coffee quality than the faster mode of using conventional machines can reach at present.Traditionally, brewed coffee needs good a few minutes to prepare, but the consumer may obtain coffee in some occasion in less than 30 seconds time.Conventional machines can not adopt soluble coffee, also is because the quick production of coffee beverage makes not obtain developing as yet in the market of the high-quality coffee of production fast from preparer.
The traditional coffee preparer has two boilers, and a boiler produces the hot water of system coffee, and another boiler is used to produce steam.Traditional wisdom is just thought can not be with the local of the identical size of existing machine or in littler place, from only producing brewed coffee with the machine of a boiler.Therefore, the design of conventional machines keeps dead state on certain hour.Coffee machine can be supplied coffee ideally under about 87 ℃ outlet temperature, but, acceptable coffee supply temperature can be up to 93 ℃.Producing in batches in the process of coffee with machine, outlet temperature must be kept, and supplies with the consumer so that guarantee coffee with the temperature of needs.
Sometimes may be difficult to accomplish in the peak period this point.The steam that needs in preparation of transdermal solutions or gels is preferably under about 100 ℃ temperature and provides.Temperature control realizes that by thermostat in the machine of prior art, heat exchange is undertaken by contacting with surrounding air in outlet, and this may be a kind of means of control temperature of poor efficiency, may cause the coffee supplied too hot.One of problem of the machine of prior art is keeping of required exhaust temperature, particularly when producing coffee in a large number.Another defective of known preparer is, the space that is occupied by machine owing to need two boilers, and hold two boilers and strengthened the space.Think in the past and can not reduce the machine occupation of land by carry out all modulation functions with a boiler.
The espresso of milk base must regularly clean and maintain keep output quality.The standard of espresso/cappuccino production depends on operator's the skill and the maintenance of equipment, and this may sell underproof coffee in the inexperienced situation of for example operator.Approximately must throw aside the coffee that filters in per 30 minutes, cause poor efficiency like this.In busy restaurant environment, this policy is often out in the cold, and this just makes remarkable underproof coffee deliver to the consumer, the sale that influence is following.
Summary of the invention
