Description

M247145 V. Creation instructions (1) [Technical field to which the new type belongs] This creation relates to a coffee machine that brews high-density coffee (such as E spress 〇) at high temperature and pressure. The coffee machine has a simplified structure and cost. Low, low failure rate, easy to transfer, brewing mellow coffee and other advantages. [Previous technology] A coffee machine for brewing high-strength coffee (such as: Espresso) should meet the requirements of about 9 standard atmospheric pressure (atm) (about 9 bar), 90 degrees Celsius-100 degrees Celsius, and a flow rate of about 10cc / sec. In order to make a mellow coffee with uniform concentration and rich in coffee fat. The water in the body and the acrosome inside the body passes through brown juice. The outflowing high temperature will cause this, so pump the bubble. Although this high, operating [new Zhinan thicker than the pressure aqueduct in the body space of the pot, the above-mentioned coffee water temperature often decomposes and the design of the world can be resolved and sells the contents of the cafe] / and the bottom of the corpse is filled with steam and is larger than the outside It is derived that the brown machine is higher than the high pressure that produces coke out. It has a closed carcass. The water can be injected into the pot to heat it. When the water reaches a certain temperature, it will be in | The higher the temperature, the greater the vapor pressure. When the boundary pressure is within a certain range, the high-temperature coffee powder installed at the bottom of the tube can form a dense kiss to achieve the purpose of high pressure and increase the water temperature. At 0 ° C, the tannins in coffee are boiled to make the coffee taste bitter. In view of the use of pumps as a power generator to produce high-pressure coffee machines, the water of coffee is sent to the coffee raw materials. However, this type of pump coffee machine has a high manufacturing rate and high maintenance expenditure. ; The burden on the φ-type coffee cart is increased. 2. New technical problems to be solved:

M247145 V. Creation Instructions (2) — This creation is to solve the problem that the high-density coffee machine in the prior art caused the decomposition of endodantanic acid to generate pyroic acid, which makes the coffee taste bitter and mixed, and the pump-type southern strength coffee machine High manufacturing cost, high selling price, high failure rate, high repair expenses, etc., in order to achieve the research and development goals of coffee taste, reduce the burden of light business, etc. This creation proposes the above design ideals, while improving the use of safety . New technical means to solve the problem: A high-density coffee brewing machine, which mainly includes a south-pressure cylinder that outputs high-pressure gas through a gas output pipe; > a cold fresh water container containing a coffee brewing machine Clean water; the gas outlet is connected to the top of the cold and fresh water container; the capacity & 〆 brewing water output pipe to output high-pressure brewing water; ° a heating tube, with a tube cap closed on a tube body to form a The closed tube is placed at the bottom of the heating source for heating, and the heating tube is built in. The heating tube is connected to the end of the heating tube with a spiral metal and connected; the control valve in the machine is connected with the brewing water output tube. The brewing system is a built-in coffee powder structure, and the brewer is connected through a pressure-relieving Kai Yi 'to allow the coffee liquid to flow out of the knot; 另一 another # _ / milk foam maker of the above heating tube, including- The spray production always leads to the inside of the heating cylinder, and the other end is protruding into a milk bottle in a gate-like manner.

Creation instructions (3) The leak The pressure switch includes a conventional body, two-end joints, a leak-proof washer, a steel ball, and a valve handle. The steel ball has a through hole. The valve handle can control the steel ball to rotate in the body to achieve the purpose of opening and closing. The surface of the steel ball has everything The groove is opposite to the water outlet end when the valve body is closed. Compared with the previous technology, the new type compares with the previous technology. Compared with the previous technology, the structure of this case is simpler than the conventional pump pressurized coffee maker, the component cost is low, and the failure rate is low. Each structure is an independent unit and can be installed in a movable manner, so it is suitable for moving and different setting environments. The mobile coffee cart is easier to install and use the creation of this case. In this case, hot water was used to heat the brewing water inside the metal heating tube to 90-100 degrees Celsius, so the temperature of the brewing water reached a maximum of 100 degrees boiling point. This temperature does not cause a large amount of tannic acid in coffee. Pyroic acid 'so can retain the aroma of coffee. " In this case, the pressure release switch of the brewer can be used to release the residual pressure in the brewer to ensure the safety when cutting. W 4 ^ U ensures that the milk foam maker in this case is replaced and the foam is used in this case.

In order to ensure the replacement of coffee powder and the safety machine during shutdown: First I: Intersect 1, the structure of this case is lower than the conventional pumped pressurized coffee booth, the component cost is low, the failure rate is low, and the high-pressure cylinder (1〇 ;: | Page 11 M247145 V. Creative Instructions (8) ------ ^ The container (20) and the heating tube (30) are independent units and installed in a movable manner. ^ ^ This is suitable for moving and different settings Environment, mobile coffee cart ί tnn and use this case. This case uses boiling water in the heating cylinder (30), moon water () to heat the heating pipe (34) to brew water (21), so brew water (21 ) The temperature reaches a boiling point of 100 degrees at most. Such a temperature does not yet cause a large amount of tannic acid in coffee to decompose into too much pyroic acid, so it can retain a fragrant flavor; 爰 Yes, this creation can brew high-concentration coffee. It meets 9 standard atmospheric pressure (atm), 90-100 degrees Celsius, and a flow rate of about 10 (^ / 3 "and other brewing conditions β. This case is more about the safety and versatility of the use. The heating cylinder (3 0 The pressure inside) is monitored by a pressure gauge (36) (as shown in the first figure), and the heating cylinder is used 30) to produce fresh milk foam, which can timely release the pressure in the heating cylinder (f 0) and increase the value of use. When the brewer (40) is closed, the ¾ pressure action ensures even more Necessary measures for safety. As shown in the eighth figure, the high-pressure cylinder and the cold fresh water container in this case can be replaced by a stand-alone high-pressure electric pump (70), which can raise at least 9 atmospheric pressure. 'The electric pump (7 The water inlet end (7 1) of 0) is connected to the clean water supply place by pipeline, and the water outlet end (7 2) after pressurization is connected to the water outlet pipe (2 2) and the flow control valve (35). One end of the tube (34) is heated to achieve the same high-pressure water output and perform the heating effect. Although this case is described with a preferred embodiment, those skilled in the art can make various changes without departing from the spirit and scope of this case. The above examples are only used to illustrate the case, not to limit the scope of the case.
