Curd is fed to the top of tower (1), accumulates therein and is severed from the bottom as blocks by guillotine (2). During accumulation the weight of the pillar of curd (assisted by vacuum in chamber (4)) causes whEy to be expressed thErefrom via perforations (5). The throughput of tower (1) can be increased by pressure feeding the curd using auger (7). Alternatively pressurised feed may be achieved by air pressure from pump (15). The air may be heated by heat exchanger (20) to 20-25 ~C to reduce friction of curd with inlet (6) and with tower (1). Warmed air may also be introduced into chamber (4).

Why it's free to use
- Filed March 6, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 6, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 6, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
