肯尼亚采购需求：小型冻干机、真空冻干机、玻璃夹套反应器、旋转蒸发仪、刮膜萃取仪、分子蒸馏仪

I'm interested in purchasing freeze dryers specifically designed for food items. I'm looking for options that can handle two different capacities: one for 30-50 kgs and another for 50-100 kgs. Could you please provide the specifications for the available models along with an estimated cost including shipping to Nairobi, Kenya? Your prompt feedback would be greatly appreciated as I'm eager to move forward with this purchase. Thank you!
