摘要： A grinding device comprises a grinding housing with mutually co-acting grinding bodies. A lower of the two grinding bodies is both driven and axially adjustable for the purpose of setting a grind size. An upper grinding body is removable. A grind size of the grinding device can be adjusted in absolute manner between a first extreme position and a second extreme position, corresponding to a fixed setting range between a minimal clearance between the two grinding surfaces and a maximum clearance between the two grinding surfaces. An extreme position of the adjustable grinding body is imposed by a stop which is encountered by the adjusting means in the relevant extreme position. A coffee machine uses the absolute grind size and/or a fine-tuning for an optimal contact time between coffee and through-flowing water.

摘要： A device for locking the micrometric adjustment of the degree of grinding in coffee grinders includes a hollow cylindrical casing for housing a lower grinding wheel carrier, which is connected to a motion transmission shaft, and for housing an upper grinding wheel carrier, which is axially movable; and a threaded ring nut engagable in the casing to adjust the position of the upper grinding wheel carrier, wherein the ring nut has at least one seat for inserting a peg for locking its rotation, and the casing has an undercut slot in which a slider cooperating with the peg is housed, the thickness of the slider being less than the thickness of the slot. A member engages the slider and causes it to rise and to interfere by friction with the upper wall of the slot.

摘要： A grinder (30) has a toolessly attached ingredient hopper assembly (50) overlying a toolessly attached fixed grinding burr (134) defining the top of a grind chamber (158) within which is received a mating rotary grinding burr (150) that is slidably mounted to a rotary drive motor (154) for adjustment relative to the fixed grinding burr (134). Adjustment is achieved automatically by control of a stepper motor (168) that pushes on the end of an elongate member (151) passing through a hollow rotary drive axle (152) and carrying the rotary grinding burr (150) at an opposite end. Start of a grinding cycle in response to actuation of a start switch is inhibited if a pair of photosensors (81, 82) do not detect location of a ground ingredient container (68) in a correct position for receipt of the ground food ingredient, if an automatically closable hopper cover lid (57) is not in a closed position or if grinding parameters, such as the fineness of the grind and the amount of ingredient to be ground has not been detected.

摘要： Disclosed is a grinder which includes a grinder assembly retained in a housing. The grinder assembly receives material for grinding such as coffee beans. Grinding burrs are provided, one of which is rotated by a grinder drive motor of the grinder assembly. The other of the burrs is generally non-rotatable with regard to the general grinding operation. The two grinding burrs are provided with grinding surfaces against which beans are ground. The grinding surfaces are spaced a desired dimension away from each other to produce a desired grind of coffee. An apparatus, system and method is disclosed for adjusting at least the generally non-rotatable burr to maintain, calibrate or otherwise adjust the dimension or gap between the grinding surfaces of the burrs.

摘要： A coffee maker includes a valve mechanism having a micro switch, an electromagnetic valve, a magnetic covering board activated by the electromagnetic valve for opening or closing a powder path, and a spring interconnecting the covering board and the electromagnetic valve. A motor-driven grinding mechanism includes two ring-shaped outer grinding members having teeth facing each other, and a spring biased inner grinding member including a hollow feed rod with a lead screw formed thereon. A powder fineness adjusting mechanism includes an adjustment lever. In a powder fineness adjustment for producing coarse coffee powder, pivoting the lever toward one direction will pivot an abutment member and move the same outward to push one grinding member for increasing a space between the grinding members filled with coffee beans to be ground. Pivoting the lever toward the other direction will produce fine coffee powder.

摘要： A grain mill includes upper and lower supports defining a chamber. An upper mill stone is disposed in the chamber and affixed to the upper support. A lower mill stone is disposed in the chamber beneath the upper mill stone and is driven about a vertical axis of rotation. The upper support cannot rotate relative to the lower support, but can move vertically relative thereto to adjust a grinding gap between the mill stones. Adjustment of the upper support is achieved by a rotatable adjusting ring having right and left-handed screw threads which engage respective threads of the upper and lower supports. The upper support comprises a cover member which carries the upper mill stone and a cover ring which is threadedly connected to the adjustment ring. The cover member is removable from the cover ring while the cover ring remains attached to the adjustment ring.

摘要： A coffee mill is incorporated in a coffee-making machine. At least one horizontal grinding unit has a casing provided with a lateral outlet which opens into a vertical discharge nozzle. The lateral outlet is located opposite to a centrifugal turbine which projects coffee powder through the lateral outlet. Provision is made opposite to lateral outlet for a vertical discharge nozzle, the bottom orifice of which opens directly above the location of a brewing receptacle and the upper portion of which has a lateral inlet ear placed opposite to the lateral outlet of the grinding unit. The discharge nozzle is provided with a deflecting inner wall which is capable of downwardly directing the coffee powder delivered by the grinding unit. The discharge nozzle is also removably mounted and may thus be readily cleaned.

摘要： A grinder refinement mechanism for use with a conventional coffee or peanut grinder is disclosed. The grinder includes the usual screw conveyor having a rotary grinding burr attached to a forward end thereof, a stationary grinding burr connected to a wall of the grinder housing and a main spring which biases the screw conveyor toward the forward end of the grinder housing against an adjustment screw projecting through an end wall. The mechanism includes a lever arm pivotally attached to an outside surface of the end wall and an electrical solenoid connected to the arm. The usual adjustment screw is replaced with a plunger element which slidably projects both into and out of the end wall and is confined between a forward end of the screw conveyor and the arm. In one condition of the solenoid, the main spring forces the screw conveyor and plunger forwardly to hold the arm against a stop screw which thus determines the desired coarse grinding condition of the grinder burrs. In the other condition of the solenoid, the arm is drawn off the stop screw to force the plunger and screw conveyor rearwardly in opposition to the main spring to a fine grinding condition of the grinder burrs. The coarse and fine grinding conditions of the grinder burrs can be precisely adjusted by the stop screw and a screw mounted on the arm which bears on the plunger. Additional solenoids may be employed in different arrangements to obtain more than two grinding conditions such as coarse, intermediate and fine grinding conditions. A relief spring connected between each of the solenoids and the arm permit the arm to flex momentarily when the grinder encounters binding or jamming to relieve such conditions.
摘要翻译：公开了一种用于常规咖啡或花生研磨机的研磨机细化机理。研磨机包括通常的螺旋输送机，其具有附接到其前端的旋转磨削毛刺，连接到研磨机壳体的壁的固定磨削毛刺和将螺旋输送机朝向研磨机壳体的前端偏压的主弹簧，通过端壁突出的调节螺钉。该机构包括可枢转地附接到端壁的外表面的杠杆臂和连接到臂的电磁螺线。通常的调节螺钉被一个柱塞元件代替，该柱塞元件可滑动地伸入和移出端壁并被限制在螺旋输送机的前端和臂之间。在螺线管的一个条件下，主弹簧迫使螺旋输送机和柱塞向前以将臂抵靠在止动螺钉上，从而确定研磨机毛刺的期望的粗磨条件。在螺线管的另一种情况下，将手臂从止动螺丝上拉出，以迫使柱塞和螺旋输送机向后相对于主弹簧向磨床毛刺的细磨状态。研磨机毛刺的粗磨和磨细条件可以通过止动螺丝和安装在支柱上的手臂上的螺丝来精确调节。额外的螺线管可以用于不同的布置以获得两个以上的研磨条件，例如粗磨，中磨和细磨条件。连接在每个螺线管和臂之间的释放弹簧允许当研磨机遇到结合或卡住以缓解这种状况时，臂瞬时弯曲。
