Vegetable and Fruit Juicer with Ceramic Auger, Secondary Pulp Pressing and Built-In Stirrer

The problem

When extracting juice from fruits and vegetables, standard machines often push wet pulp out of the discharge chute after a single pass. The leftover moisture in the dregs represents wasted produce and lowers the overall juice yield. Buyers who process large volumes of ingredients notice this loss quickly, as the dry weight of the discarded pulp remains higher than necessary.

Another common issue is separation. Freshly pressed juice tends to settle, with heavier particles sinking to the bottom of the pitcher while the lighter liquid stays on top. Users must manually stir the juice or pour it into a separate blender to mix it evenly before serving. This adds steps, requires extra equipment to wash, and slows down service in commercial or busy household settings.

Finally, feeding whole or large pieces of produce into a juicer can be awkward. Straight cylindrical chutes sometimes cause items to jam near the top, requiring users to push them down with a plunger. Open, wide chutes also present a safety concern if small hands can reach too far into the feeding area during operation.

The solution

This juicer design combines a ceramic crushing mechanism, a secondary pressing stage, and an integrated mixing function into one unit.

1. Produce is dropped into a charging aperture (3) at the top of a squeezing cylinder (2). The feed pipe uses a trapezoidal shape, narrow at the top and wider below, to guide items downward toward the crushing area.
2. Inside the cylinder, a ceramic agitating screw (11) driven by a second stirring motor (10) cuts and crushes the fruits and vegetables. The ceramic material handles the extraction process.
3. As the screw pushes the crushed material forward, juice flows down to a juice opening (7) at the bottom of the cylinder. A filter screen placed at this opening stops pulp from falling into the juice receiving cup (6) below.
4. The remaining dregs are pushed into an interface of slagging tap (4) connected to the cylinder. This interface is threaded onto the cylinder to prevent leaks during operation and allow easy removal for cleaning.
5. Inside the discharge interface, three annular convex ribs (12) work against the turning screw to compress the pulp a second time. This secondary extrusion forces remaining juice out of the dregs before they exit through the slag notch (5).
6. The extracted juice collects in the receiving cup (6), where an agitating device (8) consisting of a stirring shaft and vanes is already positioned.
7. A first stirring motor (9) inside the fuselage (1) drives the agitating device through a rotation connection block (13) mounted on the body. This stirs the collected juice automatically.
8. Both the first and second motors are direct current generators. The entire unit is managed via a control button (14) located on the top of the fuselage.

Who it is for

• Small kitchen appliance brands looking to add a slow-style juicer with a ceramic auger and built-in stirring function to their product catalog.
• Amazon sellers and e-commerce retailers sourcing differentiated home juicers that offer secondary pulp pressing and automatic mixing as distinct features.
• Juice bar and cafe operators needing a machine that extracts more liquid per batch of produce and keeps the juice mixed without manual intervention between orders.
• Wholesalers of home goods supplying stores that cater to buyers interested in kitchen appliances with specific mechanical designs rather than standard blade blenders.

How it works

The main parts

Operating steps

1. Load produce - place fruits or vegetables into the charging aperture (3) at the top of the squeezing cylinder (2).
2. Start extraction - press the control button (14) to turn on the second stirring motor (10), which rotates the ceramic agitating screw (11).
3. Crush and press - the screw cuts the produce into small pieces and crushes them further, generating juice and dregs.
4. Filter juice - the liquid passes through the filter screen at the juice opening (7) and drops into the juice receiving cup (6).
5. Secondary pressing - the screw pushes the dregs into the interface of slagging tap (4), where the three annular convex ribs (12) squeeze them again before they exit the slag notch (5).
6. Stir the juice - the first stirring motor (9) turns the rotation connection block (13), spinning the agitating device (8) inside the cup to mix the collected juice.

Applications

Home kitchens

Households preparing daily fresh juice benefit from the secondary pressing ribs, which extract more liquid from expensive organic produce. The built-in stirrer keeps the juice mixed in the cup, saving the user from washing a separate spoon or blending pitcher.

Juice bars and cafes

Commercial counters processing continuous batches need consistent yields. The ceramic screw and the three annular ribs work together to reduce the moisture left in the discarded pulp. Staff can serve the juice directly from the receiving cup since the agitating device prevents settling during busy periods.

Health food retail demonstrations

Appliance demonstrators in retail stores can show the automatic stirring feature to shoppers. Instead of stopping to shake a pitcher, the machine keeps the sample juice uniform while the presenter explains the extraction process.

Office breakrooms

Workplaces offering fresh juice stations need equipment that limits manual steps. Employees drop produce into the trapezoidal feed pipe, press the control button, and collect mixed juice without needing to learn complex assembly or cleaning routines beyond unscrewing the threaded discharge interface.

Small catering operations

Caterers preparing fresh beverages for events can use the integrated stirring function to keep large batches uniform. The threaded interface allows quick disassembly for washing between different types of fruits or vegetables during service.

Where it is less suitable

• High-volume industrial juice processing - factory lines producing thousands of liters per hour use large-scale hydraulic or centrifugal presses, not countertop auger machines.
• Hard root vegetables exclusively - while the patent mentions vegetables, capacity for extremely hard roots depends on the motor torque and ceramic strength, which are set in design and confirmed on prototypes.
• Users needing heated blending - this is a cold extraction and stirring device; it does not cook or heat the contents.
