Fruit Juice Squeezer Citrus Juicer Hand Press Heavy Duty Lemon Squeezer Manual Fruit Juicer Detachable Orange Lime Grapefruit Presser - 50 Pcs Filter Bags

If I was doing that many I'd use an old school zester (strings) and not a microplane. If you need the zest finer, chop it or process it. Then for juicing, use a press. This one isn't available anymore but just to illustrate what I mean. Longer handle for more leverage than the small ones you may be more familiar with. https://a.co/d/0gUEFnWL
