Spare Part - Oval Top Lock Nut and Spring

The Oval Top Lock Nut is available for pre-order, with shipments scheduled to resume at the end of September.  

In the meantime, the Flower Top Lock Nut is available, though if used with a lid, the hole in the center lid must be at least 2.25" in diameter.  Some older lids have an center hole which is smaller than that.  The older, smaller center holes can be enlarged by the customer in the field, or as an alternative, a Flower Top Lock Nut can be ordered with a new plastic lid.  All currently available lids have a sufficiently large center hole to accommodate any type of top lock nut.

• The Top Lock Nut and Spring controls the grinding and refining functions of the machine. When it is tightened, the stone wheels are closer to the stone base and through a shearing action, the particle size of the chocolate is broken down. But if the lock is loosened, little or no pressure is applied to the stones and so the machine is on a refining or conching setting. While the particle size of the chocolate will not change, the refining action will impact the organoleptic profile of the chocolate.

• Suitable for all Premier Chocolate Refiners (large and small countertop models), this part is made of hard plastic and stainless steel.
