摘要:
A machine (1) for making and dispensing liquid or semi-liquid food products, comprising: a container (102) for the product to be dispensed; a dispenser (103) which is connected to the container (102) and which can be turned on and off to allow or inhibit dispensing of the product from the container (102); a stirrer (105) rotatable about a respective axis of rotation (R) and mounted inside the container (102) to mix the product being processed; a thermal system (2) having a circuit with a heat exchanger fluid flowing through it and comprising, along the circuit, an evaporator (3) operatively associated with the container (102) of the product to be dispensed and including an inlet aperture (307) for the heat exchanger fluid, a discharge aperture (308) for the heat exchanger fluid, a first tubular element (301) and a second tubular element (302) coaxial with the first tubular element (301) and having an axial direction of extension and a radial direction of extension (R1), the second tubular element (302) extending at least along an axial direction parallel to the axis of rotation (R) and being disposed inside the first tubular element (301) to define an annular chamber (303) for circulating the heat exchanger fluid and defined by at least one microchannel (800), the microchannel (800) having a hydraulic diameter of between 3 mm and 13 mm.
摘要:
A machine (20) for the preparation of a cooled or heated product comprising: —a receiving seat (1) for accommodating a container (8) comprising at least part of the ingredients for the preparation of a product; —a heat exchange element (1a) arranged to be in contact with an outer wall of the container (8), when the container (8) is placed in the receiving seat (1), and —temperature sensing means (100) arranged to measure the temperature at an outer wall of the container (8) when the container (8) is placed in the receiving seat (1), the temperature sensing means (100) comprising at least two temperature sensors, a primary temperature sensor (101) arranged to measure the temperature (TS1) in proximity to an outer wall of the container (8) and a secondary primary sensor (102) arranged to measure the temperature (TS2) in a position located in the heat path through which heat travels between the inside the container (8) and the external environment.
摘要:
An ice making system includes a flavored liquid, an ice machine and a refrigerated storage bin. The ice making system continuously produces flavored ice pieces for storage in an ice storage bin. A refrigeration system cools the ice storage bin.
摘要:
A machine for making and dispensing liquid, semi-liquid and/or semi-solid food products and which includes at least a cylinder for containing and processing basic products, means for heating and cooling the cylinder wrapped around at least part of the cylinder and a mixer unit positioned inside the cylinder which is able to mix the basic products during their processing; the machine also includes a supply duct for supplying the products into the cylinder, a dispensing duct for withdrawing the food products from the cylinder and means for recirculating the products contained in the containment and processing cylinder which are able to withdraw the products from the cylinder through the dispensing duct and to return them into the cylinder through the supply duct.
摘要:
A through-flow freezer is disclosed comprising a freezing cylinder, an inlet pipe, an inlet blocking device, an air inlet, an outlet pipe and an outlet blocking device, wherein, at least in one operational mode of the through-flow freezer, the inlet blocking device and the outlet blocking device are closed such that a certain amount of mix and a certain amount of air substantially corresponding to a desired overrun in the freezing cylinder can be entrapped in the freezing cylinder by introducing air via the air inlet. Furthermore, a method for starting up a through-flow freezer is disclosed comprising the step of adding air through the air inlet until a certain amount of mix and a certain amount of air substantially corresponding to a desired overrun is entrapped in the freezing cylinder and a certain cylinder pressure is reached in the freezing cylinder before starting the cooling of the freezing cylinder.
摘要:
A method for producing of ice cream roll-ups, in which a mixture is obtained from sugar, powdered milk, glucose syrup, liquid coconut fat, powdered whey, stabiliser and water, in order to create roll-up layers, which are consecutively subject to homogenisation, pasteurisation, cooling, maturing and initial freezing with aeration followed by an initially frozen mixture being formed into a final product that is hardened and placed in a cooling chamber. The ice cream roll-up is hardened in a first hardening tunnel in an atmosphere having a temperature from - 55°C to -65°C in order to achieve a temperature not higher than -18°C in an outer layer constituting at least 25% of ice cream volume, and subsequently the ice cream roll-up is hardened in a second hardening tunnel in an atmosphere having a temperature from -40°C to -42°C in order to achieve temperature not higher than - 18°C in the total volume of the ice cream roll-up.
摘要:
A process for producing a frozen confectionery product comprising a frozen composition which contains inclusions in the form of frozen particles is provided, the process comprising: preparing a mix of ingredients having a total solids content of from 5 to 25% and containing from 0.2 to 2.0 wt% of one or more stabilisers; optionally pasteurising and / or homogenising and / or ageing the mix; freezing the mix to form frozen particles in a fragmented ice maker comprising a refrigerated barrel and a screw auger; and dosing the frozen particles into the frozen composition.
